Transfer of mitochondria from astrocytes to neurons after stroke
Neurons can release damaged mitochondria and transfer them to astrocytes for disposal and recycling. This ability to exchange mitochondria may represent a potential mode of cell-to-cell signalling in the central nervous system.

Neuronal cell types are the nodes of neural circuits that determine the flow of information within the brain. Neuronal morphology, especially the shape of the axonal arbor, provides an essential descriptor of cell type and reveals how individual neurons ...

Specialized coding of sensory, motor and cognitive variables in VTA dopamine neurons
There is increased appreciation that dopamine neurons in the midbrain respond not only to reward1 and reward-predicting cues1,2, but also to other variables such as the distance to reward3, movements4–9 and behavioural choices10,11. An important question

Knowledge Neurons in Pretrained Transformers [PDF]
Large-scale pretrained language models are surprisingly good at recalling factual knowledge presented in the training corpus. In this paper, we present preliminary studies on how factual knowledge is stored in pretrained Transformers by introducing the ...

The human attention system, similar to other networks in the brain, is of a complex nature. At any moment, our attention can shift between external and internal stimuli.

IntroductionConsumer decision-making processes involve a complex interrelation between perception, emotion, and cognition. Despite a vast and diverse literature, little effort has been invested in investigating the neural mechanism behind such processes ...

Optimizing Fixation Filters for Eye-Tracking on Small Screens
The study of consumer responses to advertising has recently expanded to include the use of eye-tracking to track the gaze of consumers. The calibration and validation of eye-gaze have typically been measured on large screens in static, controlled ...

Simple Methods for Permanent or Transient Denervation in Mouse Sciatic Nerve Injury Models
Our ability to move and breathe requires an efficient communication between nerve and muscle that mainly takes place at the neuromuscular junctions (NMJs), a highly specialized synapse that links the axon of a motor neuron to a muscle fiber. When NMJs or

Local Translation in Nervous System Pathologies
Dendrites and axons can extend dozens to hundreds of centimeters away from the cell body so that a single neuron can sense and respond to thousands of stimuli.

In Vitro Differentiation of Human Skin-Derived Cells into Functional Sensory Neurons-Like
Skin-derived precursor cells (SKPs) are neural crest stem cells that persist in certain adult tissues, particularly in the skin. They can generate a large type of cell in vitro, including neurons.
