The blood–brain barrier forms a buffer against the systemic circulation. Now drugs administered to the brain are shown to be exported by a transporter to act at peripheral sites.
An electrophysiological study in monkey primary visual cortex reveals that a late component of neural activity is correlated with perceptual awareness of an object.
Studies of populations of receptor proteins suggest that their number and location are highly regulated. Single-particle tracking of glycine receptors now reveals the direct movement of receptors between different clusters of the anchoring protein gephyrin.
A modeling study shows that inhibitory synapse plasticity, guided by simple activity-dependent rules, can lead to appropriate phase relationships within an oscillating network.
