Posited that memory is stored in different regions of the brain
Fuster
Founder of neuroscience: neurology, anterior commissure, cerebellar peduncles, internal capsule, vagus nerve
Thomas Willis
Cells that aid and modulate neuron acitvity
glial cells
Association neurons, associate sensory and motor activity within CNS
interneurons
outermost layer of gray matter making up superficial aspect of cerebrum
Cerebral cortex
initiating activities, planning, holding critical info, changing mental set, monitoring effectiveness of actions, inhibition
Prefrontal cortex
multiple maps of body space, multisensory integration
Parietal lobe
star shaped, nutritive, transports substances through blood-brain barrier, regulate synaptic activity, regulate neurotransmitter concentrations, neurotransmitter reuptake after release,
Astrocyte
small, defensive function; become phagocytes during injury, infection, degeneration
Microglial
asymmetric, forms myelin around CNS axons
Oligodendroglia
asymmetric, wraps around peripheral nerves to form myelin
Schwann
Cation (positively charged) and anion (negatively charged); attract water
ions
Malfunction of ____ channel cause neurologic diseases; site of action for toxins/drugs
ion
beginning of 3rd trimester, new synaptic connections sprout followed by pruning
Synaptogenesis
Neuron fires with ___ state > ______ > _______
Neuron fires with resting state > electrical charges > action potential
electrical charge produced when ions move across membranes through gate channels and change separation
action potential
speeds up neural impulse
myelin
part of axon not covered by myelin, tiny gaps, enables saltatory conduction
Node of Ranvier
Both genes and the environment affect brain development
epigenesis
________ are around ventricles; rapid proliferation; can generate copies of themselves which plays role in differentiated neurons and glial cells
Proliferation zones
How many layers are in the cortex
6
Class of drugs to which PCP/angel dust belongs
Phencyclidine
Neurons providing basis for re-entrant connectivity
Neurons form two-way pathways
Two tenets of modern neuroscience
Brain is organized into functionally specific areas
Neurons in different parts of nervous system are similar
Name the 8 brain networks
Arousal/wakefulness, attention, language, visuospatial, memory, executive, sensation/movement, emotion
Injury where results in perseverative behavior, field-dependence, mental rigidity, flat affect
Frontal lobe / Dorsolateral
Injury where results in behaviorally and emotionally disinhibited: euphoria and rage, impulsive
orbitofrontal frontal lobe
Injury where results in akinesis (little initiation of movement/speech), apathy, blunting
ventromedial frontal lobe
scalp electrodes reveal brain rhythms such as gamma
EEG
magnetic cortical activity; higher source localization than EEG
MEG
slices – x-ray
CAT
x-ray
CT
indirect measure, energy use
fMRI
indirect measure, energy use, glowing inject
PET
MRI technique that measure macroscopic axonal organization
DTI - diffusion tensor imaging
sleep wave - conscious mind, alertness, concentration, focus, 5 physical senses
beta waves
sleep wave - gateway to subconscious mind – deep relaxation, light meditation, creativity, learning
alpha waves
sleep wave - light sleep, REM dream state, deep meditation, intuition, memory and visual memory
theta waves
sleep wave - deep sleep, dreamless state, automatic self-healing, immune system function
delta waves
Color selective part of the eye
cones
Light selective part of the eye
rods

Wernicke
_________ lobe encodes information across sensory domains
medial temporal lobe
Decline in one or more areas of cognitive function, impacts ADLs
dementia
o Defects in short-term memory
o Issues with problem-solving, language, calculations, visuospatial skills, mood, activity, sleep, appetite
o Begins in entorhinal cortex, hippocampus
Alzheimer’s
