Q

Limbic System

A

Located in the Forebrain, Regulates emotional responses. Loosely connected network of structures located roughly along the border of the cerebral cortex and deeper subcortical areas

16
Q

Hippocampus

A

Located in the Forebrain, Part of limbic system involved in learning and memory

17
Q

Amygdala(s)

A

AAAAAAAAAAAAAAAAAAH!
-Forebrain, one in each hemisphere
Involved in memory and emotion, particularly fear and aggression

17
Q

Corpus Callosum

A

Bridge fibers that pass information between two cerebral hemispheres

18
Q

Parietal Lobe

A

Mid-Back of Forebrain
Primary Somatosensory Cortex/Registers touch

19
Q

Occipital Lobe

A

Back of Forebrain
Primary Visual Cortex/Visual processing

20
Q

Temporal Lobe

A

Below Parietal and Frontal Lobe
Primary Auditory Cortex/Auditor processing

21
Q

Frontal Lope

A

Front of Forebrain
Primary Motor Cortex/Movement of muscles

22
Q

Broca’s Area

A

Region in the frontal lobe of the dominant hemisphere, usually the left, linked to speech production

23
Wernicke's Area
Region of the temporal lobe of the dominant hemisphere linked to speech processing(language comprehension/listening)
24
Pituitary Gland
Base of the brain near Pons and Hypothalamus Releases a variety of hormones throughout the body, stimulating actions in other endocrine glands
25
Thyroid
in the front of neck and Produces hormones that regulate energy, metabolism and growth
26
Parathyroid(s)
Front of neck above Thyroid Produce Parathyroid Hormone-regulates calcium levels in blood and other parts of the body
27
Adrenal Gland(s)
it's above the kidneys and Produce hormones that regulate metabolism, immune system, stress, and other essential functions
28
Pancreas
located behind the stomach, it secretes hormones that regulate blood sugar levels, and plays role in digestion
29
Ovaries/Testies
Reproductive organs possessed by female/male animals
30
Pineal Body
it's beneath Corpus Callosum, located in the Midbrain and produces melatonin-regulates sleep and wake cycles
31
Suprachiasmatic Nucleus
A pair of grain-of-rice-sized, 20,000-cell clusters in the hypothalamus that receive light input from the retina via the optic nerve and regulate the body's circadian rhythms (sleep cycle)
32
How is rewiring an element of plasticity?
Rewiring is a plasticity mechanism that alters connectivity between neurons.
