Lemniscal Corticothalamic Feedback in Auditory Scene Analysis

Frontiers in Neuroscience, 2021
Sound information is transmitted from the ear to central auditory stations of the brain via several nuclei. In addition to these ascending pathways there exist descending projections that can influence the information processing at each of these nuclei ...

Development of parallel auditory thalamocortical pathways for two different behaviors

Frontiers in Neuroanatomy, 2010
Auditory thalamocortical connections are organized as parallel pathways that originate in different divisions of the medial geniculate body (MGB). These pathways may be involved in different functions. Surprisingly little is known about the development

Functional evidence for cone-specific connectivity in the human retina [PDF]

, 2009
NoPhysiological studies of colour vision have not yet resolved the controversial issue of how chromatic opponency is constructed at a neuronal level. Two competing theories, the cone-selective hypothesis and the random-wiring hypothesis, are currently ...

Cholinergic System Changes in Dopa‐Unresponsive Freezing of Gait in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Freezing of gait (FoG) is a debilitating mobility disturbance that becomes increasingly resistant to dopaminergic pharmacotherapies with advancing Parkinson's disease (PD). The pathophysiology underlying the response of FoG to dopaminergic treatment is poorly understood.

Variation of connectivity across exemplar sensory and associative thalamocortical loops in the mouse

eLife, 2020
The thalamus engages in sensation, action, and cognition, but the structure underlying these functions is poorly understood. Thalamic innervation of associative cortex targets several interneuron types, modulating dynamics and influencing plasticity.

How lateral inhibition and fast retinogeniculo-cortical oscillations create vision: A new hypothesis [PDF]

, 2016
The role of the physiological processes involved in human vision escapes clarification in current literature. Many unanswered questions about vision include: 1) whether there is more to lateral inhibition than previously proposed, 2) the role ...

New species and new records in Agarista (Ericaceae) from the Peruvian Andes

Nordic Journal of Botany, EarlyView.
Agarista (Ericaceae) is currently represented in Peru by three species. Here, we update this number to five, adding new taxa based on the recognition of a taxonomic novelty and new records. The new species Agarista eugeniifolia differs from all congeneric species by an abaxially sulcate midvein.

A new framework for Euclidean summary statistics in the neural spike train space [PDF]

Annals of Applied Statistics 2015, Vol. 9, No. 3, 1278-1297, 2015
Statistical analysis and inference on spike trains is one of the central topics in the neural coding. It is of great interest to understand the underlying structure of given neural data. Based on the metric distances between spike trains, recent investigations have introduced the notion of an average or prototype spike train to characterize the ...

Some investigations into non passive listening [PDF]

, 2006
Our knowledge of the function of the auditory nervous system is based upon a wealth of data obtained, for the most part, in anaesthetised animals. More recently, it has been generally acknowledged that factors such as attention profoundly modulate the ...
