Dopamine encoding of reward prediction errors naturally fluctuates over females’ reproductive cycles with estrogenic signaling due to reduced expression of dopamine reuptake proteins.

Nature Neuroscience - Liu and colleagues show that the vigor (that is, speed and amplitude) of dexterous movements is not controlled by ongoing fluctuations in extracellular dopamine within the...

Whether and how anatomically distinct regions of the superior colliculus (SC) exhibit specialisation in multisensory temporal integration to facilitate different behavioural responses are not fully un...

Neural mechanisms underlying reinforcement learning in naturalistic environments are not fully understood. Here authors show that reinforcement learning (RL) agents with hippocampal-like recurrence, u...

This randomized clinical trial evaluates outcomes following adjunctive ketamine infusions vs midazolam for depression.

We found strong evidence that antidepressants differ markedly in their physiological effects, particularly for cardiometabolic parameters. Treatment guidelines should be updated to reflect differences...

Neuropsychiatry has yet to surmount the fundamental challenge of mapping behavioral pathology to its underlying neural pathology. This gap limits the development of treatments for specific circuit pat...

Significance The combination of two-photon calcium imaging and two-photon optogenetic stimulation, termed all-optical interrogation, provides spatial and temporal precision when recording and manipula...

Often, gene therapy reviews concentrate upon specific therapeutic modalities – particularly either viral vector-mediated or a non-viral approach. Here, we draw together a comprehensive array of knowle...

UCL is consistently ranked as one of the top ten universities in the world (QS World University Rankings 2010-2022) and is No.2 in the UK for research power (Research Excellence Framework 2021).

The roles of distinct dopaminergic neuron subpopulations and the circuit projections driving their activity during threat behaviors remain incompletely understood. Here, the authors demonstrate that substantia nigra pars lateralis dopamine neurons receive selective, robust excitation from auditory and temporal association cortices, which, combined with rapid action potential firing, contributes to auditory threat conditioning.

Differences in neuroeconomic decision-making influence nucleus accumbens dopamine dynamics and reflect choice confidence during evaluation, as well as past and future value during re-evaluation, which...

Neuropsychopharmacology - Prefrontal contribution to passive coping behaviour in chronic stress and treatment by fast-acting antidepressant

Kim et al. show that 5XFAD mice exhibit persistent risk-taking and reduced behavioral flexibility in naturalistic “approach food-avoid predator” foraging paradigms. Simultaneous neural recordings reve...

In dynamic environments where stimuli predicting reward or punishment unexpectedly change, it is critical to flexibly update behavior while preserving…

A multi-cell-type drug discovery strategy targeting dysregulated gene networks in neurons and glia identified letrozole and irinotecan as a combination therapy that significantly improved memory and r...

Background Racemic ketamine and its enantiomer, esketamine, have emerged as fast-acting antidepressant options for individuals with treatment-resistant depression (TRD). Yet, despite growing clinical ...

A stereotaxic atlas of the whole mouse brain, based on a Nissl-stained cytoarchitecture dataset with isotropic 1-μm resolution, achieved through continuous micro-optical sectioning tomography, promise...
