Amphetamine reduces reward signaling by neurons in rat prefrontal cortex, but increases the stability of population dynamics, which account for animals’ increased task engagement, despite reduced reward motivation.
Instant performance recovery is possible following general anesthesia-induced unconsciousness using antagonist, and the brain dynamics return abruptly to the awake state without intermediate recovery states.
Vax1 suppresses dopaminergic neuron phenotype by inhibiting Pax6 expression in the subventricular zone of the lateral ventricle and is necessary to generate Calbindin interneurons for the postnatal olfactory bulb.
Computational modeling predicts that sleep replay plays a protective role against catastrophic forgetting by revealing synaptic mechanisms allowing overlapping populations of neurons to store multiple interfering memories.
The midbrain area for salience, reward and aversion in mouse brain harbours among the dopamine cells three subtypes somatostatin-expressing neurons that show combinatorial neurotransmitter phenotypes and interneuron properties.
