The Human Brain


2/27

The human brain starts working themoment you are born and never stopsuntil you stand up to speak in public

The right half of the brain controlsthe left half of the body. This meansthat only left handed people are intheir right mind"

It is good to rub and polish ourbrain against that of others"

Neuron Structure


4/27

Parts of Brain

Brain stem: i.e Medulla, Pons and Midbrain

Cerebellum

Hypothalamus and Pituitary gland

Cerebrum (also called the Cerebral cortex )


5/27

Brains for Instinct

Lower animals (fish, amphibians, reptiles,birds) do not do much "thinking," butinstead concern themselves with theeveryday business of gathering food,eating, drinking, sleeping, reproducing

and defending themselves. These areinstinctual processes Therefore, theirbrains reflect the major centers thatcontrol these functions.

We perform these functions as well, andso have a "reptilian" brain built into us.This involves the same brain parts of thebrain found in reptiles, namely theBrainstem and the Cerebellum.

The Brainstem

(Pathway to the Body)

Base of brain

Unconscious work

Autonomic functions(survival)


7/27

The Cerebellum

(Balance)

Little brain

Large in size

11% of brains weight Center of balance


8/27

The Higher Brain - Cerebral Cortex

The Cerebrum is the largest part of the human brain

Contains all of the centers that receive and interpretsensory information, initiate movement, analyze

information, reason and experience emotions.

The centers for these tasks are located in differentparts of the cerebral cortex, which is the outsidelayer of the cerebrum and is comprised ofgraymatter.

The inside is made up ofwhite matter.


9/27

Major Parts of the Cerebral Cortex

The Gyri (elevation) & Sulci(depression)

Several large sulci divide the cerebral

cortex into various lobes:

1.Frontal lobe

2.Parietal lobe

3.Occipital lobe and

4.Temporal lobe

11/27

The Frontal Lobes

(Problem Solving)

Largest part

Move your body

Highly developed Forms your personality


12/27

The Parietal Lobes

(Touching)

Two major divisions

Anterior and posterior

Senses hot and cold,

hard and soft, and pain.

Taste and smell

Helps integrate the senses


13/27

The Temporal Lobes

(Hearing)

Process auditory stimuli

Subdivisions

Wernickes Area Brocas Area


14/27

The Occipital Lobes

(Seeing) Located at lower central back of brain

Processes visual stimuli

brain

Taking sides.two sides that is!

Two sides or hemispheres of the brain:LEFT and RIGHT

We have two cerebral hemispheresconnected by the corpus callosum.

This is a bundle of nerves that allows eachside of the brain to communicate with eachother.

Each side of the brain processes things

differently.

It is an outdated assumption that artsy typepeople are right-brained.

T ki id


17/27

Taking sides.

how the two sides process

information that is!Left Brain

Logical Sequential

Rational

Analytical Objective

Looks at parts

Right Brain

Random Intuitive

Holistic

Synthesizing Subjective

Looks at wholes


18/27

Left Hemisphere

Processes things more in parts andsequentially

Recognizes positive emotions

Identified with practicality and rationality

Understands symbols and representations

Processes rapid auditory information fasterthan the right (crucial for separating thesounds of speech into distinct units for

comprehension) Is responsible for language development. It

develops slower in boys, that is why malesusually develop more language problemsthan females.


19/27

Right Hemisphere

Recognizes negative emotions

High level mathematicians, problem solvers, andchess players use

The non-verbal side

Responds to touch and music (sensory)

Intuitive

Responsive to color and shape

Emotional and originative


20/27

Taking sides.what information the two sides recognize!

Left Brain

Letters

Numbers

Words

Right Brain

Faces

Places

Objects


21/27

The Brain is Like Real Estate

All that matters is location,

location and location !!!!!!!!!!!!!!!!!

Symptoms depend on the area of

the brain involved, not thedisease.

Brain tumors, strokes, head

injuries can all present with the

same symptoms because of the

area of the brain involved.

Representation of various area inside the brain

25/27

Layers of the Brain

The human brain is organized into

3 interconnected layers:

Central Core : Brain for Instinct

Limbic System

Cerebral Cortex (aka the Higher Brain)
