The combination of intraneural microstimulation and 7T fMRI makes it possible to bridge the gap between first-order mechanoreceptive afferent input codes and their spatial, dynamic and perceptual representations in human cortex.
Behavior- or optogenetic-driven activation of a basolateral amygdala projection to the nucleus accumbens enhances infralimbic cortex activity and long-term fear extinction.
Using a sequential neurofeedback-arm reaching task, a new link is established among population neural activity patterns, generation of beta oscillations, and motor behavior changes.
The first comprehensive map of all excitatory inputs to the mouse striatum is presented and used to define and demarcate striatal subdivisions, including a previous unappreciated novel subdivision in the posterior striatum.
Somatosensory feedback is transmitted to many sensory and motor cortical regions within 25 milliseconds and ongoing behavioural tasks alter the spatiotemporal pattern of this perturbation-related activity, supporting rapid motor responses to attain behavioural goals.
The evidence of subspace computation in the lateral prefrontal cortex provides insights into the neural mechanisms underlying cognitive flexibility and interference between different cognitive processes.
Mirror neurons, including corticospinal neurons, in primary motor cortex of macaque monkeys, clearly dissociate between execution and observation of grasping actions while ventral premotor cortex (F5) maintains a similar representation.
Targeted optogenetic activation of small ensembles of neurons is sufficient to trigger a behavioral report while recruiting matched network suppression, suggesting exquisite sensitivity despite network mechanisms that maintain sparseness.
Neurons in human dorsal motor cortex, an area involved in controlling arm and hand movements, are also active – and show similar ensemble dynamics – during speaking.
Voluntary movements are preceded by a temporally flexible preparatory neural process that is present regardless of whether movement is initiated rapidly or thoughtfully.
