Chronic silencing of subsets of cortical layer 5 pyramidal neurons has a long‐term influence on the laminar distribution of parvalbumin interneurons and the perineuronal nets

Journal of Anatomy, Volume 246, Issue 4, Page 479-504, April 2025.
Chronic silencing of subsets of layer 5 projection neurons has distinct effects on the laminar distribution of PV interneurons and the perineuronal nets in the adult primary motor and somatosensory cortex. Abstract Neural networks are established throughout cortical development, which require the right ratios of glutamatergic and GABAergic neurons ...

High-field fMRI reveals brain activation patterns underlying saccade execution in the human superior colliculus [PDF]

, 2010
Background The superior colliculus (SC) has been shown to play a crucial role in the initiation and coordination of eye- and head-movements. The knowledge about the function of this structure is mainly based on single-unit recordings in animals with ...

Detectability index measures of binaural masking level difference across populations of inferior colliculus neurons. [PDF]

, 1997
In everyday life we continually need to detect signals against a background of interfering noise (the “cocktail party effect”): a task that is much easier to accomplish using two ears.

Autism Pathogenesis: The Superior Colliculus [PDF]

Frontiers in Neuroscience, 2019
After being exposed to visual input, in the first year of life, the brain experiences subtle but massive changes apparently crucial for communicative/emotional and social human development. Its lack could be the explanation of the huge prevalence of autism in children with total congenital blindness.

Sleep neuroimaging: Review and future directions

Journal of Sleep Research, EarlyView.
Summary Sleep research has evolved considerably since the first sleep electroencephalography recordings in the 1930s and the discovery of well‐distinguishable sleep stages in the 1950s. While electrophysiological recordings have been used to describe the sleeping brain in much detail, since the 1990s neuroimaging techniques have been applied to uncover

Impaired Auditory Temporal Selectivity in the Inferior Colliculus of Aged Mongolian Gerbils [PDF]

, 2011
Aged humans show severe difficulties in temporal auditory processing tasks (e.g., speech recognition in noise, low-frequency sound localization, gap detection). A degradation of auditory function with age is also evident in experimental animals.

Inhibition and potentiation of the exercise pressor reflex by pharmacological modulation of TRPC6 in male rats

The Journal of Physiology, EarlyView.
Abstract figure legend The majority of L4–L5 dorsal root ganglion cells innervating the triceps surae muscles of healthy rats expressed TRPC6 channels. In decerebrated rats, pharmacological inhibition of TRPC6 channels by injection of antagonists (SAR7334 or BI‐749327) into the arterial supply of the triceps surae muscles inhibited the exercise pressor

Coding of auditory space [PDF]

, 2003
Behavioral, anatomical, and physiological approaches can be integrated in the study of sound localization in barn owls. Space representation in owls provides a useful example for discussion of place and ensemble coding. Selectivity for space is broad and

Lactate and hydrogen ions play a predominant role in evoking the exercise pressor reflex during ischaemic contractions but not during freely perfused contractions

The Journal of Physiology, EarlyView.
Abstract figure legend The role of lactate and hydrogen ions in evoking the metabolic component of the exercise pressor reflex was studied in rats with either a functional pygm gene (pygm+/+) or with a non‐functional “knocked out” pygm gene (pygm−/−). The pygm gene is responsible for producing the myophosphorylase enzyme which catalyses the breakdown ...

CONCURRENT fMRI WITH MICROSTIMULATION TO IDENTIFY NEURAL CONNECTIVITY OF THE MACAQUE SUPERIOR COLLICULUS [PDF]

, 2006
Brain connectivity in many species has commonly been investigated using tract tracing techniques. These experiments require the animals to be sacrificed and do not allow for future electrophysiological studies to be performed in the same subject. In this
