How animals sense and properly avoid predators remains incompletely understood. Here, Jiang et al. show that the B cell co-receptor, CD20 also functions as an olfactory receptor and mediates the innate avoidance of predator derived odors.
How the feedforward information from the nose and feedback from the cortex interact in the olfactory bulb is not fully understood. Here, by imaging olfactory sensory neurons and cortical projections to the olfactory bulb, the authors show that sensory transformations contained within both streams.
Repetitive audio-visual stimulation, or sensory flicker, can modulate oscillations in a non-invasive manner. Here the authors demonstrate the potential of flicker in individuals with epilepsy undergoing intracranial seizure monitoring.
Innate fear-like responses are thought to involve the amygdala, but here a tetra-synaptic pathway is identified that mediates odour-evoked innate fear in mice.
Infant attachment to the mother in rodents and monkeys is shown to rely on regulation of hypothalamic oxytocin release by a serotonergic projection from the raphe nucleus.
