Dissecting the Role of GABA Neurons in the VTA versus SNr in Opioid Reward

open access: yesJournal of Neuroscience, 2020
Opioid reward has traditionally been thought to be mediated by GABA-induced disinhibition of dopamine (DA) neurons in the VTA. However, direct behavioral evidence supporting this hypothesis is still lacking.

The effect of non-Gaussianity on error predictions for the Epoch of Reionization (EoR) 21-cm power spectrum [PDF]

open access: yes, 2015
The Epoch of Reionization (EoR) 21-cm signal is expected to become increasingly non-Gaussian as reionization proceeds. We have used semi-numerical simulations to study how this affects the error predictions for the EoR 21-cm power spectrum.
