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.
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.
