This study utilized fiber photometry to explore dorsal striatal calcium and dopamine activity during drug seeking in rats trained on fixed-ratio (FR) or second-order (SO) reinforcement schedules, which represent goal-directed or habit-like cocaine-seeking behavior, respectively. The researchers identified distinct neural activity signatures in the dorsal striatum across these reinforcement conditions,

This study aimed to determine if oscillatory neuronal activity, represented by local field potentials (LFPs), varies between cortical layers and if these laminar patterns are consistent across different cortical areas and species. Researchers analyzed LFPs from intracortical recordings, from 14 different cortical areas, in rhesus macaque monkeys using multi-contact laminar probes.

This new pre-print publication from Tobias Teichert et al., titled "Volumetric mesoscopic electrophysiology: a new imaging modality for the non-human primate" which was recently published in bioRxiv. This study presents an approach for recording local field potentials (LFPs) across an entire monkey hemisphere, providing a unique functional profile that combines high temporal resolution with a wide field of view.

Check out the new publication from Maanasa Jayachandran et al., titled "Nucleus Reuniens Transiently Synchronizes Memory Networks at Beta Frequencies," which was recently published in Nature Communications. This study sheds new light on episodic memory-based decision-making processes, elucidating the critical role of synchronized network oscillations and the thalamic nucleus reuniens (RE) in mediating prefrontal-hippocampal memory interactions.

Development of a Synchronous Recording and Photo-Stimulating Electrode in Multiple Brain Neurons
In this study, the researchers aimed to develop a compact and ultra-light opto-electrode capable of simultaneously recording and stimulating multiple brain regions. To achieve this, they employed cutting-edge technologies, including micro-nanofabrication quartz glass modules, laser-cutting electrode microwires, a customized laser-perforated steel sheet array, and a customized printed circuit board (PCB).
