C.) Microelectrode

If kittens are raised in an environment that contains only verticals, you would predict that most of the neurons in their visual cortex would respond best to the visual presentation of a A.) chain link fence. B.) solid wall. C.) picket fence. D.) brick wall.

C.) picket fence.

Brain-imaging techniques can determine all of the following EXCEPT... A.) areas of the brain activated during cognitive tasks. B.) localization of brain activity in response to a specific stimulus. C.) the structure of individual neurons. D.) patterns of blood flow in the brain.

C.) the structure of individual neurons.

Early studies of brain tissue that used staining techniques and microscopes from the 19th century describes the "nerve net." These early understandings were in error in the sense that the nerve net was believed to be...

Continuous

Which of the following is consistent with the idea of localization of function? A.) Neurons in different areas of the brain respond best to different stimuli. B.) Specific areas of the brain serve different functions. C.) Brain areas are specialized for specific functions. D.) All of the above.

D.) All of the above.

Which of the following statements is the most accurate with regard to specificity coding? A.) Specificity coding is one of the areas that is only theoretical and not applied, and thus there is no way to know if it truly exists in human beings. B.)Research has found that specificity encoding does occur for lower animals, such as dogs and cats, but has not found this phenomenon to exist in human beings. C.) It is probably accurate, which explains why the human nervous system contains over one hundred quadrillion neurons. D.) It is unlikely to be correct because there are too many stimuli in the world to have a separate neuron for each.

D.) It is unlikely to be correct because there are too many stimuli in the world to have a separate neuron for each.

Neurons that respond to specific qualities (e.g., orientation, movement, and length) that make up objects are called...

Feature Detectors

You are walking down the street and see a really nice car drive by. You notice many features if it: its color, movement, shape, location, and so forth. All of these features are processed...

Neural circuits

A grandmother cell responds...

ONLY to a specific stimulus

When conducting an experiment on how stimuli are represented by the firing of neurons, you notice that neurons respond differently to different faces. For example, Arthur's face causes three neurons to fire, with neuron 1 responding the most and neuron 3 responding the least. Roger's face causes three different neurons to fire, with neuron 7 responding the least and neuron 9 responding the most. Your results support ____ coding.

Population/Sparce

If the intensity of a stimulus that is presented to a touch receptor in increased, this tends to increase the ________ in the receptor's axon.

Rate of nerve firing

The idea of a grandmother cell is consistent with...

The gap that separates two different neurons

The Occipital Lobe

The part of the Cerebral Cortex where the visual cortex is located

The Temporal Lobe

Where signals are received from the auditory system
