Two different analysis approaches for measuring neural synchronization to natural music revealed strongest synchronization to musical spectral flux as opposed to the more commonly used amplitude envelope.

Neurons in the OFC signal expected reward specifically when this information is used for learning rather than for choosing, and silencing these neurons impairs use of this information to learn.
A new tool enables measuring feeding and locomotion simultaneously which will enable insights into environmental, developmental, neuronal, and genetic factors underlying behavioral regulation.
Category-selective intracerebral neurophysiological activity in low- and high-frequency bands show unprecedented corresponding spatial, functional, and timing properties in the human brain.
A computational model of decision making suggests that the dorsolateral prefrontal cortex's role in self-control is more associated with evidence accumulation processes than with inhibition or modulation of value.
Early and late visual deprivation trigger a redeployment mechanism that reallocate part of the processing typically tagging the preserved senses (i.e. the temporal cortex for auditory stimulation) to the occipital cortex deprived of its most salient visual input.
Physiological analysis reveals that during voluntary contraction Ia afferent input have a lesser facilitatory effect on motor neurons in humans with chronic incomplete spinal cord injury compared with control subjects.

The age-dependent shift of prefrontal excitation-inhibition (E-I) ratio toward inhibition causes sparser and decorrelated activity, while its impairment might relate to neurodevelopmental disorders.
A viral heliorhodopsin from Emiliania huxleyi virus 202 (V2HeR3) is a light-activated proton transporter, which has the potential to depolarize the host cells by light, possibly to overcome the host defense mechanisms or to prevent superinfection.
