Neural firing demonstrates phase precession in human hippocampal complex, allowing representation of spatial and non-spatial information for navigation.
Liquid–liquid phase separation of CaMKII and glutamate receptor clusters in postsynaptic membranes might mediate trans-synaptic alignment with the presynaptic vesicle release machinery.
The neocortex and the thalamus are connected by looping circuits, enabling cortical function. In this Review, Gordon Shepherd and Naoki Yamawaki examine the patterns of connectivity between the major types of cortical and thalamic neurons and how these cortico-thalamo-cortical loops relate to corticocortical circuits.
Dendritic spines can be considered to embody algorithms that underlie various brain functions. Here, Kasai et al. review spine dynamics and their roles in various brain functions, compare these dynamics with parallels in machine learning and describe how disrupted dynamics may contribute to mental disorders.
Sociopolitical changes regarding cannabis and its potential harm for vulnerable populations raise concern as more pregnant women and teens use cannabis. Hurd and colleagues discuss neurobiological effects of cannabis exposure during development and highlight an epigenetic link for synaptic reprogramming.
Acute cannabis exposure modulates numerous aspects of neurocognitive function; however, the effects experienced by individuals are highly variable. Ramaekers and colleagues here review the neural basis of cannabis-induced neurocognitive changes and response variability, and consider the legal, therapeutic and societal implications.
