Final Details Flashcards
Evoked potentials depend on:
Physical properties of the stimulus
Grandmother cell
multimodal
Rather than relying on reaction times, lesion methods tend to rely on which of the following?
Error rates
Posner (1978) called study of the time-course of information processing in the human nervous system
Mental Chronometry
Which imaging method measures the white matter connectivity between regions?
DTI Diffusion Tensor Imaging
Protons from which type of molecule found in the human body form the main basis for the MRI signal?
H20
The principle of cognitive subtraction holds that it is possible to infer functionally specialized brain regions by:
Identifying regions activated by an experimental, but not baseline, task
fNIRS (functional near infrared spectroscopy)
Measures BOLD response (Blood-Oxygen Level-Dependent Contrast)
Talairach coordinates define locations in the brain according to x, y, and z values, with the origin lying at a region called the:
Anterior Commisure
The process of smoothing spreads the raw activation of a given voxel to neighboring voxels according to which function?
Gaussian Distribution
By choosing a more conservative significance level (P value) in neuroimaging analysis, one runs the risk of failing to detect true regions of activation, an error known as:
Type II error
According to Farah et al. (2014) how good is fMRI at separating truthful versus deceitful answers?
69% - 100%
Which nucleus projects to primary auditory cortex along the thalamo-cortical route?
Medial Geniculate Nucleus
One way of dealing with variability in the acoustic signal in the brain is:
Categorical Perception
In the Biased Competition Model at what stage does serial processing emerge?
Motor Stages
Neglect is associated with lesions to the:
Right Inferior Parietal Lobes
The ability to report on the content of awareness is referred to as:
Access Consciousness
Which of the following accurately describes the changes in the basal ganglia motor circuit of patients with Parkinson’s disease:
Increasing the output of the indirect pathway, and decreasing the output on the direct pathway
The primary motor cortex corresponds to which Brodmann area?
Brodmann Area 4
The frontal eye fields can be found in which Brodmann area?
Brodmann Area 8
The lateral premotor cortex has been associated with:
acting with objects in the environment
The human analogue of monkey area F5 is believed to be in:
Broca’s Area
Neurons in which of the following brain region area code action-relevant properties of objects (e.g. specific shapes, sizes, and orientations)?
Anterior Intraparietal Area
A sharp edge of a particular object indicates that it is useful for cutting. The property of objects that allow us to make this inference is called:
Affordance
