New paper out in @pnas.org Thalamic CGRP neurons form a spinothalamic pain pathway relaying pain signal to the amygdala & insular, but not sensory cortex to encode the affective dimension of pain. Huge congrats to first author Sukjae Kang & coauthors. www.pnas.org/doi/10.1073/...

Psilocybin’s lasting action requires pyramidal cell types and 5-HT2A receptors - Nature

A pyramidal cell type and the 5-HT2A receptor in the medial frontal cortex have essential roles in psilocybin’s long-term drug action.

Some glutamatergic synapses show decreased release probability (Pr) at high firing rates due to vesicle depletion or VGCC feedback inhibition. In contrast, neuromodulator vesicles exhibit increased Pr, enabling frequency-dependent encoding of distinct information via transmitter switching.

Encoding opposing valences through frequency-dependent transmitter switching in single peptidergic neurons

Peptidergic neurons often co-express fast transmitters and neuropeptides in separate vesicles with distinct release properties. However, the release dynamics of each transmitter in various contexts ha...
