When the monkey is presented with a relevant target and an irrelevant distractor stimulus, the initial activity of MT and MST neurons exhibits very little selectivity for the target (Ferrera and Lisberger 1997b; Recanzone and Wurtz 2000). The pursuit eye velocity evoked after comparable short delays ...

The crucial involvement of endocannabinoids in these functions just began to emerge fro ...

The integrative capacity of the circadian system appears to be time-limited to the extent that, under test conditions explored to date, if a photic stimulus is sufficient to produce a maximal phase shift, more photons at the same time or up to 2 h later have no additional effect on phase shift magni ...

... The same motor neurons (MNs) and extraocular muscles are active for all types of eye movements (e.g. saccades, pursuit and vergence).

In fact, initial RT-PCR analyses detected the expression of leptin receptor mRNA in GnRH-producing GT1-7 cells (Magni et al., 1999), which might be suggestive of direct actions on GnRH neurons.

Feature detection (nervous system)

Feature detection is a process by which the nervous system sorts or filters complex natural stimuli in order to extract behaviorally relevant cues that have a high probability of being associated with important objects or organisms in their environment, as opposed to irrelevant background or noise. Feature detectors are individual neurons – or groups of neurons – in the brain which code for perceptually significant stimuli. Early in the sensory pathway feature detectors tend to have simple properties; later they become more and more complex as the features to which they respond become more and more specific. For example, simple cells in the visual cortex of the domestic cat (Felis catus), respond to edges – a feature which is more likely to occur in objects and organisms in the environment. By contrast, the background of a natural visual environment tends to be noisy – emphasizing high spatial frequencies but lacking in extended edges. Responding selectively to an extended edge – either a bright line on a dark background, or the reverse – highlights objects that are near or very large. Edge detectors are useful to a cat, because edges do not occur often in the background “noise” of the visual environment, which is of little consequence to the animal.
