Two new studies expand the optogenetic repertoire by showing light-induced inhibition of synaptic release and control of gene transcription and chromatin modifications.
Psychology and neuroscience studies have shown that memory is a reconstructive process that is susceptible to distortion. Lacy and Stark summarize the evidence and discuss how this insight could be applied to police and courtroom procedures.
Oligodendrocytes support neurons by releasing exosomes that are internalized by neurons, and the cargo that they contain is shown to provide metabolic support under conditions of cellular stress.
Cheng and Ji show that in a mouse model of Alzheimer's disease, new spatial memory formation by hippocampal place cells is disrupted by an inability to encode external environmental information and by dominating internally generated brain activity.
A study reveals a signalling pathway in the mouse cortex that immobilizes mitochondria at nascent presynaptic sites in developing axons and thereby promotes terminal axon branching.
A new study reveals that an interaction between Ca2+/calmodulin and the vesicle-priming protein MUNC13-1 has a crucial role in replenishment of the presynaptic readily releasable pool of vesicles after depletion by high-frequency stimulation.
