Adaptive tuning functions arise from visual observation of past movement

Visual observation of movement plays a key role in action. For example, tennis players have little time to react to the ball, but still need to prepare the appropriate stroke. Therefore, it might be useful to use visual information about the ball trajectory to recall a specific motor memory. Past visual observation of movement (as well as passive and active arm movement) affects the learning an...

Visual System: How Does Blindsight Arise?

Some patients can discriminate unseen visual stimuli within a field defect caused by damage to the primary visual cortex. The pathways for this 'blindsight' have never been established, but recent studies implicate hitherto overlooked cells in the thalamic LGN.

Diverse strategies engaged in establishing stereotypic wiring patterns among neurons sharing a common input at the visual system's first synapse.

Sensory circuits use common strategies, such as convergence and divergence, typically at different synapses, to pool or distribute inputs. Inputs from different presynaptic cell types converge onto a common postsynaptic cell, acting together to shape neuronal output (Klausberger and Somogyi, 2008). Also, individual presynaptic cells contact several postsynaptic cell types, generating divergence...

Mammalian Sleep Dynamics: How Diverse Features Arise from a Common Physiological Framework

Mammalian sleep varies widely, ranging from frequent napping in rodents to consolidated blocks in primates and unihemispheric sleep in cetaceans. In humans, rats, mice and cats, sleep patterns are orchestrated by homeostatic and circadian drives to the sleep-wake switch, but it is not known whether this system is ubiquitous among mammals. Here, changes of just two parameters in a recent quantit...

Evidence that Circuits for Spatial and Color Vision Segregate at the First Retinal Synapse

wavelengths extended into the surround. However, it decreased firing when middle wavelengths covered both center and surround. Complementary types were also found: centers tuned to middle wavelengths with Different psychophysical " channels " mediate our per-surrounds tuned to long wavelengths, and centers tuned ception of fine spatial patterns and color. The spatial to short wavelengths with s...
