Infrared Neural Stimulation Elicits Distinct Molecular Pathways in Astrocytes Based on Laser Pulse Parameters

open access: yesAdvanced Biology, EarlyView.
Infrared (IR) light evokes distinct calcium and water transport responses in astrocytes, depending on stimulation duration and protocol. This study uses widefield imaging and pharmacology to reveal differential engagement of astroglial signaling pathways.

The Effects of Ethosuximide on Amino Acids in Genetic Absence Epilepsy Rat Model

open access: yesJournal of Pharmacological Sciences, 2006
.: Genetic absence epilepsy rats from Strasbourg (GAERS), a selectively inbred strain of Wistar rats, has been validated as an experimental model for human absence epilepsy. In this model, systemic administration of ethosuximide (ETX) was shown to reduce

Comparing Offline Decoding Performance in Physiologically Defined Neuronal Classes [PDF]

open access: yes, 2016
Objective: Recently, several studies have documented the presence of a bimodal distribution of spike waveform widths in primary motor cortex. Although narrow and wide spiking neurons, corresponding to the two modes of the distribution, exhibit different ...

A posture subspace in primary motor cortex

open access: yes
SummaryTo generate movements, the brain must combine information about movement goal and body posture. Motor cortex (M1) is a key node for the convergence of these information streams. How are posture and goal information organized within M1’s activity to permit the flexible generation of movement commands?

Functional Integration of Different‐Sex Gonad Transplants Into the Adult Mouse Hypothalamic Pituitary Gonadal Axis

open access: yesAdvanced Biology, EarlyView.
This study introduces and investigates different‐sex gonad transplants in a mouse model of gender‐affirming hormone therapy. Ovaries and testes implanted into gonadectomized adults exhibit gametogenesis and steroidogenesis independent of the sex of the host.

Suppressing Systemic Interference in fNIRS Monitoring of the Hemodynamic Cortical Response to Motor Execution and Imagery

open access: yesFrontiers in Human Neuroscience, 2018
Hemodynamic response to motor execution (ME) and motor imagery (MI) was investigated using functional near-infrared spectroscopy (fNIRS). We used a 31 channel fNIRS system which allows non-invasive monitoring of cerebral oxygenation changes induced by ...

Differential effects of dual and unihemispheric motor cortex stimulation in older adults [PDF]

open access: yes, 2013
Bihemispheric transcranial direct current stimulation (tDCS) is thought to upregulate excitability of the primary motor cortex (M1) using anodal stimulation while concurrently downregulating contralateral M1 using cathodal stimulation.

A Spatially Resolved View on the Aging Substantia nigra: An Exploratory Proteomic Study

open access: yesAdvanced Biology, EarlyView.
Although aging is the most important risk factor for several neurodegenerative diseases, the molecular effects of physiological aging are still understudied. By applying spatially‐resolved proteomic analyses of the human substantia nigra pars compacta, alterations in vesicular trafficking and mitochondrial proteins are observed, as well as reduced ...
