DOI: 10.1016/j.neuroimage.2017.10.066
Abstract: &NA; Speech perception may be underpinned by a hierarchical cortical system, which attempts to match “external” incoming sensory inputs with “internal” top‐down predictions. Prior knowledge modulates internal predictions of an upcoming stimulus and exerts its… read more here.

DOI: 10.1016/j.neuroimage.2019.03.076
Abstract: Ketamine is a unique drug that has psychedelic and anesthetic properties in a dose-dependent manner. Recent studies have shown that ketamine anesthesia appears to maintain the spatiotemporal complexity of cortical activation evoked by transcranial magnetic… read more here.

DOI: 10.1038/s41467-024-55315-6
Abstract: The brain must maintain a stable world model while rapidly adapting to the environment, but the underlying mechanisms are not known. Here, we posit that cortico-cerebellar loops play a key role in this process. We… read more here.

DOI: 10.1371/journal.pone.0217966
Abstract: Many computational theories have been developed to improve artificial phonetic classification performance from linguistic auditory streams. However, less attention has been given to psycholinguistic data and neurophysiological features recently found in cortical tissue. We focus… read more here.

DOI: 10.3389/fnins.2022.1060172
Abstract: Differences in the timing and intensity of sounds arriving at the two ears provide fundamental binaural cues that help us localize and segregate sounds in the environment. Neural encoding of these cues is commonly represented… read more here.

DOI: 10.7554/elife.105112
Abstract: Spiking activity along synaptic circuits linking primary somatosensory (S1) and motor (M1) areas is fundamental for sensorimotor integration in cortex. Circuits along the ascending somatosensory pathway through mouse hand/forelimb S1 and M1 were recently described… read more here.
