In most cases people understand the location of the areas of the brain that are used for specific purposes but not the place of the other pieces.

The use of every part of the mind differs depending on the person. The structure of the mind is an indication of that part of the mind is responsible for which function. Gyrus - The biggest area of the brain and is in charge of motor function, vision and language.

The gyrus also processes the words that you hear. The gyrus also plays a part in language since it is the section of the mind that understands the meaning of words.

Thalamus - This part of the mind has three major pieces. Another two main elements are the thalamus and the corpus callosum. The thalamus joins the left and right hemispheres of the brain and is also where the cerebrum which controls muscle movement connects with the cerebellum, which controls the motor controller of the body.

In the event that you should look at someone and flip a light round to illuminate the face you would see their eyes, mouth and the form of their face. When a person is faced with a specific situation they activate the parietal lobes.

Temporal Lobes - The temporal lobes are responsible for recognizing, naming and remembering faces. The temporal lobes are also in charge of hearing and recognizing noise. If you turned on a tv to watch a movie and the picture went out there would be a possibility that you missed seeing some thing. Globus Pallidus - The globus pallidus is a portion of the brain which contains two parts.

The most well-known region of the globus pallidus is that the amygdala, which controls emotions and memories. Another area of the globus pallidus is the thalamus, which can be located close to the base of their skull. Occipital Lobes - This part of the brain is situated just above the eyes and is responsible for motion, eyesight and being able to differentiate colour.

The parietal lobes include the area we use to discover colour. The occipital lobes may be seen when someone looks up and seems down and it allows them to be able to focus and point. Parietal Cortex - The region of the brain that is responsible for facial recognition is that the parietal cortex. It's the part of the brain that regulates facial recognition.

The part of the brain which controls our sense of touch is the somatosensory cortex.Related to topology: star topologymesh topologynetwork topologybus topologyring topology. Topographic study of a given place, especially the history of a region as indicated by its topography. Medicine The anatomical structure of a specific area or part of the body.

Mathematics a. The study of certain properties that do not change as geometric figures or spaces undergo continuous deformation. These properties include openness, nearness, connectedness, and continuity. The underlying structure that gives rise to such properties for a given figure or space: The topology of a doughnut and a picture frame are equivalent. Computers The arrangement in which the nodes of a network are connected to each other.

Mathematics the branch of mathematics concerned with generalization of the concepts of continuity, limit, etc. Mathematics a branch of geometry describing the properties of a figure that are unaffected by continuous distortion, such as stretching or knotting. Former name: analysis situs. Mathematics maths a family of subsets of a given set S, such that S is a topological space. Computer Science the arrangement and interlinking of computers in a computer network.

Physical Geography the study of the topography of a given place, esp as far as it reflects its history. Medicine the anatomy of any specific bodily area, structure, or part. The mathematical study of the geometric properties that are not normally affected by changes in the size or shape of geometric figures.

In topology, a donut and a coffee cup with a handle are equivalent shapes, because each has a single hole. The branch of mathematics that deals with the properties of shapes and surfaces. Switch to new thesaurus. Mentioned in? References in periodicals archive? Topology is a branch of mathematic that deals with the specific definitions given for spatial structure concepts, compares different definitions and explores the connections between the structures described on the sets.

MediaTek Inc. This feedback mechanism is called the full-feedback topology in [12], which incurs an unacceptable feedback overhead penalty. He covers set-theory and algebra preliminaries, topologymeasure and integration, functional analysis and convexity, and applications. According to the results, the new topology in [10] has good performance, which has lower loss than most topologies and short switching time. The series is capable of power levels up to W.Mostly French, they emphasized an axiomatic and abstract treatment on all aspects of modern mathematics in Elements de mathematique.

Representative topics are the structure theory of 3-manifolds and 4-manifolds, knot theoryand braid groups. This can be regarded as a part of geometric topology.

Introduction to Piecewise-Linear Topology

It may also be used to refer to the study of topological spaces of dimension 1, though this is more typically considered part of continuum theory. A number of advances starting in the s had the effect of emphasising low dimensions in topology. Thurston's geometrization conjectureformulated in the late s, offered a framework that suggested geometry and topology were closely intertwined in low dimensions, and Thurston's proof of geometrization for Haken manifolds utilized a variety of tools from previously only weakly linked areas of mathematics.

Vaughan Jones ' discovery of the Jones polynomial in the early s not only led knot theory in new directions but gave rise to still mysterious connections between low-dimensional topology and mathematical physics. Hamilton 's Ricci flowan idea belonging to the field of geometric analysis. A surface is a two-dimensionaltopological manifold. The most familiar examples are those that arise as the boundaries of solid objects in ordinary three-dimensional Euclidean space R 3 —for example, the surface of a ball.

On the other hand, there are surfaces, such as the Klein bottlethat cannot be embedded in three-dimensional Euclidean space without introducing singularities or self-intersections. The classification theorem of closed surfaces states that any connected closed surface is homeomorphic to some member of one of these three families:. The surfaces in the first two families are orientable.

It is convenient to combine the two families by regarding the sphere as the connected sum of 0 tori. The number g of tori involved is called the genus of the surface.

The surfaces in the third family are nonorientable. Each point in T X may be regarded as an isomorphism class of 'marked' Riemann surfaces where a 'marking' is an isotopy class of homeomorphisms from X to X. In mathematicsthe uniformization theorem says that every simply connected Riemann surface is conformally equivalent to one of the three domains: the open unit diskthe complex planeor the Riemann sphere.

In particular it admits a Riemannian metric of constant curvature. This classifies Riemannian surfaces as elliptic positively curved—rather, admitting a constant positively curved metricparabolic flatand hyperbolic negatively curved according to their universal cover. The uniformization theorem is a generalization of the Riemann mapping theorem from proper simply connected open subsets of the plane to arbitrary simply connected Riemann surfaces.

A topological space X is a 3-manifold if every point in X has a neighbourhood that is homeomorphic to Euclidean 3-space.A topological space is a set endowed with a structure, called a topologywhich allows defining continuous deformation of subspaces, and, more generally, all kinds of continuity. Euclidean spacesand, more generally, metric spaces are examples of a topological space, as any distance or metric defines a topology. The deformations that are considered in topology are homeomorphisms and homotopies.

A property that is invariant under such deformations is a topological property. Basic examples of topological properties are: the dimensionwhich allows distinguishing between a line and a surface ; compactnesswhich allows distinguishing between a line and a circle; connectednesswhich allows distinguishing a circle from two non-intersecting circles.

The ideas underlying topology go back to Gottfried Leibnizwho in the 17th century envisioned the geometria situs and analysis situs. The term topology was introduced by Johann Benedict Listing in the 19th century, although it was not until the first decades of the 20th century that the idea of a topological space was developed. The motivating insight behind topology is that some geometric problems depend not on the exact shape of the objects involved, but rather on the way they are put together.

For example, the square and the circle have many properties in common: they are both one dimensional objects from a topological point of view and both separate the plane into two parts, the part inside and the part outside. This result did not depend on the lengths of the bridges or on their distance from one another, but only on connectivity properties: which bridges connect to which islands or riverbanks.

Similarly, the hairy ball theorem of algebraic topology says that "one cannot comb the hair flat on a hairy ball without creating a cowlick.

Mladen Bestvina, Lecture 1: PL Morse Theory Part I

To deal with these problems that do not rely on the exact shape of the objects, one must be clear about just what properties these problems do rely on. From this need arises the notion of homeomorphism. Intuitively, two spaces are homeomorphic if one can be deformed into the other without cutting or gluing.

A traditional joke is that a topologist cannot distinguish a coffee mug from a doughnut, since a sufficiently pliable doughnut could be reshaped to a coffee cup by creating a dimple and progressively enlarging it, while shrinking the hole into a handle. Homeomorphism can be considered the most basic topological equivalence. Another is homotopy equivalence.

This is harder to describe without getting technical, but the essential notion is that two objects are homotopy equivalent if they both result from "squishing" some larger object. An introductory exercise is to classify the uppercase letters of the English alphabet according to homeomorphism and homotopy equivalence.

The result depends on the font used, and on whether the strokes making up the letters have some thickness or are ideal curves with no thickness. The figures here use the sans-serif Myriad font and are assumed to consist of ideal curves without thickness. Homotopy equivalence is a coarser relationship than homeomorphism; a homotopy equivalence class can contain several homeomorphism classes.Will be clean, not soiled or stained.

This course would be suitable as a second course in topology with a geometric flavour, to follow a first course in point-set topology, andi erhaps to be given as a final year undergraduate course.

Some results from algebraic topology are needed for handle theory and these are collected in an appendix. These appendices should enable a reader with only basic knowledge to complete the book. We have omitted acknowledgements and references from the main text and have collected these in a set of "historical notes" to be found after the appendices.
