Output neurons in the mushroom body of the fruit fly brain encode the positive or negative survival value of stimuli, enabling insects to choose adaptive approach and avoidance behaviors through associative learning.
Resting-state MEG-activity and MRS-GABA/Glx measurements reveal that there is a significant shift in excitability during the course of schizophrenia, involving hyperexcitability during the onset and a reduction at chronic stages.
Rostromedial tegmental neurons encode motivational valence and opponent responses across a wide range of affective stimulus modalities, while also driving dopamine inhibition and conditioned place aversion to aversive stimuli.
Perceived imminence of threat and resulting intensity of defensive responses during serial compound stimulus conditioning are determined by auditory stimulus salience, not cue sequence as recently reported.
Oligodendrocytes in white matter use Kir4.1 inwardly rectifying potassium channels to prevent extracellular potassium accumulation, enabling neurons to sustain repetitive firing and limiting the initiation of seizures.
