Three-dimensional mapping of the neural circuitry that controls movement of a marine worm in response to light provides insights into the evolution of complex visual systems.
To establish a trade-off between the speed and accuracy of a decision, neurons in lateral intraparietal cortex combine evidence bearing on the decision with a signal that incorporates the cost of time into the decision-making process.
Zebrin-positive cerebellar Purkinje cells fire at lower frequencies than zebrin-negative cells, indicating that cerebellar circuits are not physiologically homogeneous.
Crystal structures of an archaeal homologue of mammalian glutamate transporters in apo and ion-only bound outward- and inward-facing states reveal ion-coupled conformational changes supporting mechanisms of coupling, gating, and transport.
Male and female mice respond differently to the same pheromone signals, and the representation of these sensory stimuli by neurons in the medial amygdala correlates precisely with the differences in behavior.
The first complete 3D structures of mouse cholinergic neurons reveal the length and complexity of their axons, while calculations suggest that equivalent axons in the human brain are approximately than 100 meters long.
Retrograde tracing of the neural circuits that control movement of the jaw and tongue reveals how shared premotor neurons help to ensure coordinated muscle activity.
