Researchers show freezing behavior associated with feat is associated with an internally generated brain state that manifests in sustained 4 Hz oscillatory dynamics in the dorsal medial prefrontal cortex-basolateral amygdala circuits.
A new report in Science identifies a neural circuit in the dorsomedial prefrontal cortex of mouse brains that may play a key role in social dominance. Using optogenetics, researchers were able to target neurons in the dmPFC to help boost a mouse's chance of 'winning' in an aggressive encounter.
Researchers propose a new theory of memory formation, reporting memory storage does not rely on the strengthening of connection between memory cells, but on the pattern of connections that form within the first few minutes of an event.
A new neuron labeling technique allows researchers to obtain a snapshot of their activity at any moment in time. The new approach could provide new insights into neural functioning by offering better precision than current, more long term, labeling techniques.
Using optogenetics to stimulate the amygdala, researchers intensify the desire to consume cocaine in rats.
Using optogenetics to activate dopamine receptors in the ventral tegmental area could help people regain consciousness following general anesthesia, researchers report.
