Babytwins Study Sweden (BATSS): A multi-method infant twin study of genetic and environmental factors influencing infant brain and behavioral development

<p>Twin studies can help us understand the relative contributions of genes and environment to phenotypic trait variation including attentional and brain activation measures. In terms of applying methodologies like electroencephalography …

Transient dopamine neuron activity precedes and encodes the vigor of contralateral movements

<p>Dopamine neurons (DANs) in the substantia nigra pars compacta (SNc) have been related to movement vigor, and loss of these neurons leads to bradykinesia in Parkinson’s disease. However, it remains …

Central nervous system hypomyelination disrupts axonal conduction and behaviour in larval zebrafish

<p>Myelination is essential for central nervous system (CNS) formation, health and function. As a model organism, larval zebrafish have been extensively employed to investigate the molecular and cellular basis of …

Ligands binding to the cellular prion protein induce its protective proteolytic release with therapeutic potential in neurodegenerative proteinopathies

<p>The cellular prion protein (PrPC) is a central player in neurodegenerative diseases caused by protein misfolding, such as prion diseases or Alzheimer’s disease (AD). Expression levels of this GPI-anchored glycoprotein, …

Basal forebrain parvalbumin neurons modulate vigilant attention.

<p>Attention is impaired in many neuropsychiatric disorders and by sleep disruption, leading to decreased workplace productivity and increased risk of accidents. Thus, understanding the underlying neural substrates is important for …

Flexible Simultaneous Mesoscale Two-Photon Imaging of Neural Activity at High Speeds

<p>Understanding brain function requires monitoring local and global brain dynamics. Two-photon imaging of the brain across mesoscopic scales has presented trade-offs between imaging area and acquisition speed. We describe a …

Redundant neural circuits regulate olfactory masking

<p>Olfactory masking is a complex olfactory response found in humans. However, the mechanisms whereby the presence of one odorant masks the sensory and behavioral responses elicited by another odorant are …

Loss of nigral excitation of cholinergic interneurons contributes to parkinsonian motor impairments

<p>Cai et al. find that partial degeneration of dopamine inputs in mice differentially alters how remaining SNc terminals regulate cholinergic interneurons via dopamine and glutamate transmission across the dorsomedial and dorsolateral …
