Hippocampo-septal inhibitory feedback controls the medial septal circuit as a function of brain state, pyramidal cell activity and movement speed.

This study shows that hippocampo-septal feedback inhibits the medial septal circuit based on hippocampal activity and movement speed, without being essential for theta rhythm generation.

Cholinergic-dopaminergic synergy and antagonism shape prediction-error broadcasting

The paper investigates how cholinergic and dopaminergic pathways interact in reward prediction-error signaling through optogenetic and chemogenetic experiments in mice.

Parvalbumin-expressing basal forebrain neurons mediate learning from negative experience

This study identifies a role for parvalbumin-expressing basal forebrain neurons in associative learning from negative experiences through calcium imaging and optogenetic experiments.

Behavioral, neural and ultrastructural alterations in a graded-dose 6-OHDA mouse model of early-stage Parkinson's disease

This study characterizes early-stage behavioral, neuronal, and ultrastructural changes in a graded-dose 6-OHDA mouse model of Parkinson's disease, showing dose-dependent motor deficits and dopaminergic neuron loss.

Cholinergic neuronal responses to probabilistic outcome-predicting stimuli follow a weighed, unsigned prediction error model and anticipate behavioral responses

This study shows that basal forebrain cholinergic neurons respond to probabilistic outcome-predicting stimuli based on a weighted, unsigned prediction error model, and their activation predicts behavioral responses.

OPETH: Open Source Solution for Real-time Peri-event Time Histogram Based on Open Ephys

OPETH provides real-time visualization of neuronal spike times relative to external events, aiding in the identification of neuron types and behaviorally responsive populations during electrophysiology experiments.

Non-bursting non-rhythmic neurons of the ventral pallidum form cell assemblies and respond to reward and punishment during Pavlovian conditioning

Distinct synchronization, cortical coupling and behavioural function of two basal forebrain cholinergic neuron types

The paper identifies two distinct basal forebrain cholinergic neuron types with different firing patterns and behavioral roles in mice.
