Term
| extrastriate visual areas |
|
Definition
| Visual areas that lie outside the striate cortex (V1), and are considered secondary visual areas. |
|
|
Term
|
Definition
| The neurons of the olfactory bulb |
|
|
Term
|
Definition
| A condition resulting from destruction of the primary visual cortex in one hemisphere. The patient is unaware of any visual stimulation in the contralateral visual field |
|
|
Term
|
Definition
| Part of midbrain involved in auditory processing |
|
|
Term
|
Definition
| The ingration of information from more than one sensory modality, such as when watching someone speak |
|
|
Term
|
Definition
| A region in external space in which a person fails to perceieve a stimulus following neural damage. They often occur following lesions of the area V1. |
|
|
Term
|
Definition
| A subcortical visual structure. It recieves input from the retinal system and is interconnected with the subcortical and cortical systems. It plays a key role in visuomotor processes and may be involved in the inhibitory component of reflexive attentional orienting. |
|
|
Term
|
Definition
| Perceptual analysis that emphasizes the component parts of an object. Reading is a good example. |
|
|
Term
| category specific deficits |
|
Definition
| Recognition impairment that is restricted to a certain class of objects. |
|
|
Term
|
Definition
|
|
Term
|
Definition
| An area of the brain located in the ventral surface of the temporal lobe in the fusiform gyrus that responds to selective stimuli, such as faces. |
|
|
Term
|
Definition
| A nueron or small set of neurons tuned for a specific percept (apple). Like, grandmother cell. |
|
|
Term
|
Definition
| Perceptual analysis that emphasizes the overall shape of an object. Face perception has been hypothesized to be hte best example of this. |
|
|
Term
|
Definition
| A negative evoked response in the EEG signal that occurs about 170 ms after the onset of a stimulus |
|
|
Term
|
Definition
| A neurological syndrtome in which the patient has great difficulty comparing visual information to guide her actions, even though she s unimpaired in her ability to recognize objects. Optic ataxia is associated with lesions of the parietal lobe. |
|
|
Term
| view-dependent frame of reference |
|
Definition
| A theory based on the idea that perception involves recognizing an object from a certain viewpoint. |
|
|
Term
|
Definition
| The neurons that terminate on muscle fibers, causing contractions that produce movements. Originate in the spinal cord and exit through the ventral root of the cord. |
|
|
Term
|
Definition
| A device that uses the interpretation of neuronal signals to perform desired operations with a mechanical device outside the body. |
|
|
Term
|
Definition
| Neurological syndrome characterized by loss of skilled or purposeful movement that cannot be attributed to weakness or an inability to innervate the muscles. |
|
|
Term
|
Definition
| Also known as the pyramidal tract. A bundle of axons that originate in the cortex and terminate monosynaptically on alpha motor neurons and spinal interneurons in the spinal cord. |
|
|
Term
|
Definition
| A collection of motor tracts that originate in various subcortical structures, including whether the vestibular nucleus and the red nucleus. These are important for maintaining posture and balance. |
|
|
Term
|
Definition
| A distributed network of neurons that respond not only to one's own action, but also to perceived actions. |
|
|
Term
|
Definition
| A secondary motor area that plays an important role in the production of sequential movements...especially those that have been well learned. |
|
|
Term
|
Definition
| The registration of inputs in sensory buffers and sensory analysis stages. |
|
|
Term
|
Definition
| The process by whih memory representations become stronger over time. IT is believed to include changes in the brain system participating in the storage of information |
|
|
Term
| distributed representation |
|
Definition
| The idea that information may be stored in large populations of neurons located in relatively widespread regions of the brain. This idea is in contrast to the idea that the representations of of some items in memory are stored in discrete, highly localized sets of neurons. |
|
|
Term
|
Definition
| A memory that does not contain episodic awareness of the prior event, but is recognized by the feeling that the item was seen before. |
|
|
Term
|
Definition
| Knowledge to which we typically have no conscious access, such as motor and cognitive skills (procedural memory) |
|
|
Term
| perceptual representation system |
|
Definition
| A form of nondeclartive memory, acting within the perceptual system, in which the structure and form of objects and words can be primed by prior experience and can later be revealed through implicit memory tests. |
|
|
Term
|
Definition
| The result of acquisition and consolidation of information which create and maintain, respectively, a permanent record. |
|
|
Term
|
Definition
| The utilization of stored information to create a conscious representation or to execute a learned behavior like a motor act. |
