Functional brain scans of human participants show that the brain encodes other people's attention in enough richness to distinguish whether that attention was directed exogenously (stimulus-driven) or endogenously (internally driven).
Ascending and descending cortico-cortical inputs are stronger on projection neurons that project back to the source of the inputs, forming selective interareal loops in deep but not superficial cortical layers.
A new imaging modality is described that can simultaneously record from several dishes without using robotics, which enables researchers to perform high-throughput, continuous measurements on biological samples.
Excitatory synapses that occur further away from the postsynaptic cell soma exhibit greater neurotransmitter release probability, which appears to improve signal transfer fidelity for high-frequency afferent firing.
Inhibitory neurons in the hypothalamus and amygdala push and pull on the midbrain vocal gating circuit to trigger and suppress ultrasonic vocalization (USV) production in the mouse.
Single cells are believed to be incapable of complex forms of learning, but reconsideration of historical studies and more recent developments suggest that this orthodoxy must now be reconsidered.
A combination of in vivo models and imaging techniques reveals the distribution of guidance cues and their mechanisms of action during commissural axon navigation of intermediate target.
Transcranial low-intensity ultrasound applied in block design and at low duty cycles and longer sonication durations can safely and non-invasively suppress human motor-evoked potentials, possibly via GABA-A-mediated inhibitory pathways.
Micropatterned differentiation of human ESCs generates gastrulation cell types – germ layers, extraembryonic, and primordial germ cells with primate characteristics – that show conserved sorting behaviors when dissociated and reseeded as single-cell mixture.
