Largest portion of brain-makes up 80%

Has Right & left sides

Responsible for mental functions

Precentral gyrus

Located in frontal lobe

Motor control

Controls opposite side of body

ex) A stroke on the right side effects the left

In parietal lobe

for somatic sensation

Temporal

Occipital

Insula

1. Temporal- vision

2. Occipital- Auditory (hearing)

3. Insula- (deep tissue) for memory, auditory and pain

MRI

FMRI

1.  MRI- shows gray & white matter + CSF

2. FMRI- can see part of brain working the most by looking at blood flow

1. Alpha- Active & relaxed.

-in parietal lobe

2.  Beta- Visual

-in frontal lobe

3. Theta- In sleep

-occipital & temporal

4. Delta- In sleep

-all lobes

In left inferior frontal gyrus

Slow, poorly articulated speech

Motor aspect

Only speech is affected-can understand normally

left superior temporal gyrus

Speech with no meaning

A person who has this can't understand

Speech originated in Wernicke's area and is sent to Broca's

Broca's area sends words to motor cortex for movement of approipriate muscles

Short term memory

Long term memory

Short- recent events sent to long term with memory consolidation

Long- Must use over and over to have long term

Conrols all emotions

There are few synaptic connections between the limbic system and cerebral cortex.

-this is why its hard to control emotions

AKA- mesencephalon

1. Superior Colliculi- vision

2.  Inferior Culliculi- Aduitory

3.  Cerebral penduncles (no description in notes)

4. Red Nucleus- motor

5.  Substantia Nigra- Motor

AKA- Rhombencenphalon

-made of metencephalon and myelencephalon

-made of pons and cerbellum

-sensory motor to/from the spine

Apneustic & Pneumotaxic respitory control centers are here

-made of medulla oblangata

-Ascending & descending tracts pass through medulla

1. Asscending tracts- sensory crossover info. 

2. descending tracts-

a. Corticopinal

or

 b. pyramidal

-descend directly to spinal cord from cerebral cortex
