Brain regions associated with retrieval of structurally coherent visual information
Article Abstract:
A three-dimensional object is perceived by the parts of inferior temporal cortex of the brain system that are specifically meant for the reproduction of recognizable visual materials. Research conducted on the neural systems by positron emission tomography has established that blood flow to the inferior temporal gyrus and adjacent fusiform significantly increases when a person is asked to make decisions about possible objects, indicating that the left hippocampal/parahippocampal region is involved in responses to novel stimuli. However, attempts to decide on impossible objects did not generate a noticeable blood flow increase.

Cortical activity reductions during repetition priming can result from rapid response learning
Article Abstract:
Experimental support for an alternative hypothesis, in which reduced cortical activity occurs as subjects rapidly learn their previous responses, is provided. The ability to rapidly learn one's prior responses to recurrent stimuli has strong adaptive value and may be largely unavoidable consequence of deliberative processing in the service of response goals.

Fast neurotransmitter release triggered by Ca influx through AMPA-type glutamate receptors
Article Abstract:
A study was conducted to show that GABA release from A17 cells in the rat retina does not depend on voltage-gated calcium channels (VGCCs) or membrane depolarization. The results reveal a fast synapse that operates independently of VGCCs and membrane depolarization and reveal a previously unknown form of feedback inhibition within a neural circuit.
