Neuro 710: Brodmann's areas + review

frontal lobe corresponds with

Brodmann area 4

Premotor corresponds with

Brodmann Area 4: discrete voluntary movements

Area 6: movement programming

Area 8: conjugate eye movements

lesions of premotor (brodmann area 6) causes

apraxia, inability to perform purposeful movement

even though no paralysis exists

Parietal lobe corresponds with

Brodmann Areas 3,1,2: somatosensory information

Area 43: taste

temporal lobe corresponds with

Brodmann Area: 41 hearing

Wernicke (Area 22): language understanding and formulation

Broca’s Area includes

Brodmann areas 44 and 45

Occipital lobe corresponds with

Brodmann area 17: vision

Areas 18, 19: visual association

lesion of the right temporal lobe can lead to

impair learning and memory of visually based

information (Brodmann areas 20, 21, 37)

Chromatophilic substance is found in the

______________

neuronal cell bodies

Terminal arborizations are found in the

___________

neuronal axons

A membrane maintains its resting potential mainly

because of

the sodium-potassium pump

in multiple sclerosis, periods of remission are

thought to be due to

spontaneous appearance of Na+ channels

__________ has occurred when a neuron is

stimulated by more than one terminal

Spatial summation

A neuronal circuit where incoming information is

spread around or amplified is

diverging

The neurilemma is found on the

_______________

axons of the PNS

To understand what we see and hear, we use

areas of the brain called

association areas

This system is important when you study because

it can filter out distractions

Reticular formation

This devastating disease causes destruction of

motor neurons in the ventral horn of the spinal

cord.

Amyotrophic lateral sclerosis (ALS)
