Ways to Study the Brain

1. Case Study
2.Animal Studies
3. Record Electrical Activity (EEG)
4. Neuroimaging

2

Animal Studies

-Removal of different brain parts or lesion/ destroying to see what happens
-Stimulate different parts while animal is alive

3

Types of neuroimaging

-PET
-fMRI
-MRI

4

Evolution of the Brain

-Evolution across time, not a lifetime
-Most complex organ in the body
-The older the brain is our history, the more simple it is
-The newer it is in history, the more complex
-Layers of complexity added over time

5

Parts of the Brainstem

-Medulla
-Pons

6

Pons

-Coordinates basic movement
-Sleep paralysis & Circadian rhythms (REM stage)
-Blocks messages from going to the brain or down the spinal chord
-So we don't hurt ourselves when we sleep

7

Limbic System parts

-Hippocampus
-Amygdala
-Hypothalamus

8

Hippocampus

-Stores long-term memory (LTM)
-Pushes information into LTM
-Active during REM stage
-Reason why a good nights sleep is important

9

Cortical Lobes

-Frontal
-Parietal
-Occipital
-Temporal

10

Cerebrum vs. Cortex

-Cortex= thin covering of the cerebrum, does thinking
-2 Hemispheres
-4 lobes on each hemisphere
-Cerebrum= 85% of brain weight
-300 trillion synaptic connections

11

Structure of Cerebral cortex

-Wrinkled (gyruses and Sulcuses)
-Creates increased surface area
-Geographically separated by lobes

12

Where are association areas?

-Everywhere!
-Surrounding primary input locations

13

Frontal Association Area

-Judgement
-Planning
-Personality
-Processing new memories

14

Parietal Association Areas

-Mathematics
-Spacial reasoning

15

Temporal Association Areas

-Facial recognition

16

Occipital Association Area

-Complex visual processing
-Color & object recognition

17

Visual Perception Track

-Enables us "to think about the world"
-Recognize and plan our future actions

18

Visual Action Track

-Guides our moment-to-moment movements

19

Left Hemisphere

-Determines cause and effect
-Reasoning, interpreting , calculating
-Speaking (processing speech too)
-Interprets language quickly and literally

20

Right Hemisphere

-Recognition of faces
-Perceptual tasks
-Making inferences
-Modulating speech(to make meaning clear)
-Orchestrate our sense of self

21

Left Hemisphere vs. Right Hemisphere

-NO ONE IS LEFT OR RIGHT BRAINED
-Info about left and right hemispheres comes from split brain surgeries

22

Language areas of the Cerebral Cortex

-Broca's area
-Frontal lobe
-Speech production
-Very detailed mouth-motor movements
-Wernicke's Area
-Temporal lobe
-Language comprehension (meaning)

23

Visual Wiring

-Left eye--> Right Hemisphere
-Right eye--> Left Hemisphere
-Data received is then shared between hemispheres (cannot be done w/o a corpus Callosum

24

Conscious Sequential Processing

-Processes serially (one after another)
-Slower
-Requires attention
-Good at solving new problems
*Reason why we cannot multi-task
