UPDATE | WITH COMPLETE SOLUTION
The lesion analysis method used in studies of human brain function primarily
involves Answer - testing patients with brain damage to identify cognitive brain
mechanisms
Localization of mental functions in the brain is an idea that gained support
from: Answer - Paul Broca's studies of patients with language disorders
Korbinian Brodmann used _______ techniques to document 52 regions of the
brain that differed in ________ Answer - tissue staining/cytoarchitectonics
The temporal lobe likely bears this name because Answer - it lies beneath the
area of the scalp where hair grays with age
The central sulcus is an anatomical landmark that separates the ____ lobe from
the ____ lobe Answer - frontal/parietal
Communication between the two hemispheres of the brain occurs mainly
through the Answer - corpus callosum
All of the following terms refer to the same cortical region that processes visual
input EXCEPT: Answer - Heschl's gyrus
, The part of the thalamus that is most important in relaying information from
the retina to the primary visual cortex is the Answer - lateral geniculate
nucleus
Following a focal brain injury, a patient shows great difficulty in discriminating
tones that differ in sound frequency (high vs low). Which area of the cortex is
most likely affected? Answer - the superior temporal lobe
Areas of the brain where neural activity is relatively high are characterized by
Answer - increased regional blood flow
You are interested in a particular type of neuron in the occipital lobe that you
believe is responsible for processing information about motion. What type of
neurophysiological technique would best allow you to assess this hypothesis in
a living animal? Answer - single-cell recording
The term _______ is used to describe the situation in with patient group 1
(e.g., brain lesion in area A) is impaired on task X and unimpaired on task Y, and
patient group 2 (e.g., brain lesion in area B) is unimpaired on task X and
impaired on task Y. Answer - Double dissociation
A patient has an injury to the parietal lobe and has a selective deficit in
processing information about the spatial location of visual stimuli (it. no object
perception deficit). You hypothesize that this region of the brain is distinct in
function from other visual areas in the occipital lobe, in which you suspect
object information is processed. In order to establish the difference between
the two functions and two brain regions, you would need to find another
person who had damage to the ______________________ Answer - occipital
lobe and had only an object perception deficit
The technique known as _________ can be used to induce virtual (temporary)
lesions in healthy humans. Answer - TMS (transcranial magnetic stimulation)
