Neurotransmitters articles from across Nature Portfolio

Little is known about the synaptic organization of associative cortical structures such as the medial prefrontal cortex. Here, the authors use two-photon optogenetic stimulation to obtain a detailed cellular resolution map of functional synaptic connectivity of the mouse medial prefrontal cortex, finding unique spatial patterns of local-circuit connectivity in neurons that project to the basolateral amygdala.

NMDA receptors are glutamate-gated ion channels that regulate fast signaling in the brain. Here, the authors show that the opening and closing patterns of the channel derive from the action of two gates that are regulated by distinct subunits.

Through their widespread connectivity, cholinergic projection neurons in the basal forebrain can modulate diverse cognitive functions. In this Review, Ananth and colleagues provide a comprehensive overview of the development, organization and function of different populations of basal forebrain cholinergic neurons.

Hansen et al. compile and share an atlas of neurotransmitter receptor/transporter densities in the human cortex and show that receptor achitecture reflects brain structure, function, dynamics, cognitive specialization and disease vulnerability.
