Traumatic brain injury (TBI): a wound to the brain that results from a blow to the head
{
Slide 8
Scientific study of the relationship between behavior and the brain
|
Draws from many disciplines, including anatomy, biology, pharmacology, and philosophy
|
We learn how the brain function from studying people with brain injury
Experimental results from neuropsychological investigations can be used to identify
traumatic brain injury impairments
|
Neuropsychology
{
Fell down five flights of stairs
|
CT Scan revealed bleeding on the right and left sides of his brain
|
Neuropsychological testing found impaired scores for memory and attention
|
Specific impairment
L.D. reported difficulties in multitasking, easy frustration and annoyance, inability to
smell and taste, and decreased interest in socialization
|
L.D.
{
Portrait: Traumatic Brain Injury
Two ideas that influence experimental and theoretical investigations of brain function
{
The brain is the source of behavior
|
The Brain Hypothesis
{
The unit of brain structure and function is the neuron
|
The individual neurons are important in that they are what control behaviour
|
The Neuron Hypothesis
{
Brain= Old English word for tissue in skull
|
Hemispheres are connected by commissures, the largest is the corpus callosum
Composed of two symmetrical hemispheres, the right hemisphere and the left
hemisphere
|
Inner hollow tube filled with cerebrospinal fluid (CSF) (cushions the brain and may play a
role in removing metabolic waste)
|
Outer layer of wrinkled tissue known as cerebral cortex
|
What is the brain?
{
The Brain Hypothesis
Slide 13
{
Cortex is divided into four lobes: frontal, temporal, parietal, & occipital
{
Gyri are the folds of the cortex and sulciare the creases (deep ones are called fissures -
longitudinal and lateral fissures)
{
The Human Brain
Cerebral Cortex
Performs higher functions like thinking, perception and planning
Forebrain
|
Performs regulatory and movement producing functions
Brainstem
|
Going further down you get into more basic functions eg. Balance and breathing
|
Connected to brainstem and descends down the back
Performs regulatory and movement producing functions
Spinal Cord
|
Forebrain
Functionally:
