Targeting CA2 Perineuronal Nets Restores Recognition Memory and Theta Oscillations in Aged Mice

Aging Cell, Volume 24, Issue 9, September 2025.
Targeting CA2 perineuronal nets restores social/non‐social recognition memory and theta oscillations in aged mice: Aged mice displayed deficits in both social and object recognition memory, which were accompanied by enhanced perineuronal nets (PNNs) density and reduced theta power in the dCA2 region.

Sources of cholinergic input to the inferior colliculus [PDF]

Neuroscience, 2009
We combined retrograde tracing with immunohistochemistry for choline acetyltransferase to identify the source of cholinergic input to the inferior colliculus (IC) in guinea pigs. Injection of a retrograde tracer into one IC labeled cells in many brainstem nuclei.

Effect of Unilateral Acoustic Trauma on Neuronal Firing Activity in the Inferior Colliculus of Mice

Frontiers in Synaptic Neuroscience, 2021
Neural hyperactivity induced by sound exposure often correlates with the development of hyperacusis and/or tinnitus. In laboratory animals, hyperactivity is typically induced by unilateral sound exposure to preserve one ear for further testing of hearing

Stereological analysis of cholinergic neurons within bilateral pedunculopontine nuclei in health and when affected by Parkinson's disease

Brain Pathology, Volume 35, Issue 5, September 2025.
(A) PPN‐cholinergic neurons degenerate during PD. We stereologically counted their rostro‐caudal distribution in post‐mortem PPNs in health versus PD. (Bi) Serial PPN‐containing samples were cholinergic antibody‐DAB stained. (Bii) Only DAB‐stained neurons on green lines and inside the box were counted.

Frequency Coding of Multisensory Integration in the Local Field Potentials of the Medial Pulvinar

European Journal of Neuroscience, Volume 62, Issue 5, September 2025.
ABSTRACT The pulvinar is a posterior thalamic nucleus, with a heterogeneous anatomo‐functional organization. It is divided into four parts, including the medial pulvinar, which is densely connected with primary unisensory and multisensory cortical regions, and subcortical structures, including the superior colliculus.

An Overrepresentation of High Frequencies in the Mouse Inferior Colliculus Supports the Processing of Ultrasonic Vocalizations

PLoS ONE, 2015
Mice are of paramount importance in biomedical research and their vocalizations are a subject of interest for researchers across a wide range of health-related disciplines due to their increasingly important value as a phenotyping tool in models of ...

Neural Plasticity and Hearing‐Speech Development in Children with Auditory Brainstem Implants for Congenital Hearing Loss Due to Severe Inner Ear Malformation

Advanced Science, Volume 12, Issue 29, August 7, 2025.
Data from a prospective cohort with 112 auditory brainstem implant users are analyzed. Younger age at implantation (<3 years), less severe inner‐ear malformation (common cavity, cochlear aplasia, and hypoplasia), and more intraoperative eABR evoked electrodes (≥60%) are associated with better hearing and speech outcomes.

Microvascular organization of the cat inferior colliculus [PDF]

Hearing Research, 2011
Brain neural activity depends critically on the blood supply to a given structure. The blood supply can differ within and between divisions, which may have functional significance. We analyzed the microvascular organization of the cat inferior colliculus (IC) to determine if the capillary distribution is homogenous throughout.

GABA(A)-mediated inhibition modulates stimulus-specific adaptation in the inferior colliculus. [PDF]

PLoS ONE, 2012
The ability to detect novel sounds in a complex acoustic context is crucial for survival. Neurons from midbrain through cortical levels adapt to repetitive stimuli, while maintaining responsiveness to rare stimuli, a phenomenon called stimulus-specific ...
