Nanosymposia offer abstract submitters an innovative way to create and propose slide-based sessions similar to a symposium. Just like poster presenters, those seeking a nanosymposium can link presentations together with colleagues to form their own session. A nanosymposium consists of abstracts from multiple labs with a common topical interest.

Binocular disparity is used for perception and action in three dimensions. Neurons in the primary visual cortex respond to binocular disparity in random dot patterns, even when the contrast is inverted between eyes (false depth cue). In contrast, neurons in the ventral stream largely cease to respond to false depth cues. This study evaluated whether GABAergic inhibition is involved in suppressing false depth cues in the human ventral visual cortex. We compared GABAergic inhibition (GABA+) and glutamatergic excitation (Glx) during the viewing of correlated and anticorrelated binocular disparity in 18 participants using single-voxel proton magnetic resonance spectroscopy. Measurements were taken from the early visual cortex (EVC) and the lateral occipital cortex (LO). Three visual conditions were presented per voxel location: correlated binocular disparity, anticorrelated binocular disparity, or a blank gray screen with a fixation cross. To identify differences in neurochemistry, GABA+ or Glx levels were com...

Spasticity is a major health problem for patients with moderate to severe traumatic brain injury (TBI). Following TBI, the onset of spasticity and its secondary muscular and orthopedic sequellae is rapid, and can begin as early as one week following inj...

Patients with Parkinson’s disease (PD) are known to have considerable voice and speech impairments that begin to manifest early in the disease progression. The common marmoset (Callithrix jacchus) is a target species for PD model development. These New ...

Reduced ability to maintain body temperature in colder environments may contribute to the development of obesity in adulthood.

Retinal ganglion cell (RGC) axons provide direct input into several brain regions, including the dorsal lateral geniculate nucleus (dLGN), which is important for image-forming vision, and the ventrolateral geniculate nucleus (vLGN), which is associated with nonimage-forming vision. Through both activity- and morphogen-dependent mechanisms, retinal inputs play important roles in the development of dLGN, including the refinement of retinal projections, morphological development of thalamocortical relay cells (TRCs), timing of corticogeniculate innervation, and recruitment and distribution of inhibitory interneurons. In contrast, little is known about the role of retinal inputs in the development of vLGN. Grossly, vLGN is divided into two domains, the retinorecipient external vLGN (vLGNe) and nonretinorecipient internal vLGN (vLGNi). Studies previously found that vLGNe consists of transcriptionally distinct GABAergic subtypes distributed into at least four adjacent laminae. At present, it remains unclear whet...
