Subthalamic plasticity helps mice squelch innate fear responses

When the animals learn that a perceived threat is not dangerous, long-term activity changes in a part of the subthalamus suppress their instinctive fears.

Double-duty neurons in primary olfactory cortex pick up on more than just scent

The cells recognize not only odors, such as bananas and black licorice—but also images and words associated with those smells, according to single-neuron recordings from 17 people.

How ‘walking fish’ feel, taste hidden food with their legs

Fins-turned-legs in sea robins are innervated with touch-sensitive neurons and taste-receptor-rich cells that can detect prey buried in the sand, according to new research.

Visual perception improves in the blink of an eye

Blinking—long considered a problem the brain must overcome to produce seamless vision—may actually be more of a feature than a bug, new research suggests.

Individual neurons tune to complex speech sounds and cues

Neuropixels arrays implanted in people reveal nuances of speech perception and production that confirm results from brain-surface recordings and can even predict what someone is about to say.

Monkey studies throw wrench into decade-old idea about movement’s effect on visual cortex

Movements that boost activity in the visual cortex of mice have the opposite or no effect in marmosets and macaques, prompting questions about whether mice are a suitable model for the primate visual system.

Claims of necessity and sufficiency are not well suited for the study of complex systems

The earliest studies on necessary and sufficient neural populations were performed on simple invertebrate circuits. Does this logic still serve us as we tackle more sophisticated outputs?
