Decreased incubation of fentanyl seeking in the absence of proximal drug-paired stimuli.

Treating substance use disorders is difficult as individuals often resume substance use during abstinence. One potential factor contributing to the recurrence of substance use is incubation of drug craving. Specifically, individuals report higher levels of craving when presented with drug-paired stimuli across abstinence, although this effect is largely absent in opioid-dependent individuals.

Poisson Variational Autoencoder.

Variational autoencoders (VAEs) employ Bayesian inference to interpret sensory inputs, mirroring processes that occur in primate vision across both ventral (Higgins et al., 2021) and dorsal (Vafaii et al., 2023) pathways.

Is the impact of spontaneous movements on early visual cortex species specific?

Recent studies in non-human primates do not find pronounced signals related to the animal's own body movements in the responses of neurons in the visual cortex. This is notable because such pronounced signals have been widely observed in the visual cortex of mice. Here, we discuss factors that may contribute to the differences observed between species, such as state, slow neural drift, eccentricity, and changes in retinal input.
