A parallel neuronal network architecture ensures control of basic feeding reflex circuits via integration of crossmodal sensory information to filter multiple biological events and enhance meaningful behavioral choice.
Sensory neurons in the olfactory system develop from two different regions of the ectoderm, the olfactory placode and the cranial neural crest, whereas sensory neurons within the eye and ear develop from just one region.
Neural activity in the orbitofrontal cortex (OFC) represents incidental stimulus-stimulus associations, providing additional evidence for OFC having a role in cognition beyond functions centered on processing value or biological significance.
A recurrent network model trained to transcribe temporally scaled spoken digits into handwritten digits proposes that the brain flexibly encodes time-varying stimuli as neural trajectories that can be traversed at different speeds.
In nematode worms, the length of the male refractory period–the time between matings–is regulated by multiple transmitters including dopamine, which both promotes ejaculation and reduces the activity of males post-copulation.
