TWiN explores how pregnancy leads to modifications in brain structure and function that may prepare the mother for parenting. Hosts: Vincent Racaniello, Jason Shepherd, and Vivianne Morrison Click arrow to playDownload TWiN 054 (39 MB .mp3,…
Joseph Paton and Felipe Rodrigues join TWiN to explain how they used temperature manipulation to alter the speed of neuronal dynamics in the dorsal striatum of rats, a manipulation that selectively slowed down or sped up time perception, illuminating the mechanisms of time-based decisions.
Mauro Costa-Mattioli joins TWiN to discuss the results of a placebo controlled, double blind clinical trial of a probiotic which improved social behavior but not autism severity in children with ASD.
TWiN reviews altered somatosensory reactivity, which is frequently observed among individuals with autism spectrum disorders (ASD), and in mouse models the developmental timing of aberrant touch processing can predict the manifestation of ASD-associated behaviors in mouse models.
TWiN reviews experiments which show that SARS-CoV-2 triggers the up-regulation of synaptic components and perturbs local electrical field potential in cerebral organoids, organotypic culture of human brain explants and post-mortem brain samples from individuals with COVID-19.
TWiN 49: Mirror, mirror on the wall, who’s the fairest mouse of all?

TWiN welcomes mice to the elite club of ‘self-aware’ animals, with a study demonstrating a mirror-induced self-directed behavior in mice resembling visual self-recognition.
TWiN describes a study that reveals activation of endogenous retroviruses in oligodenroglia from patients with traumatic brain injury.
TWiN reviews an amazing study of a man who was paralyzed after a spinal cord injury and regained the ability to walk after implantation of a brain-spinal cord interface.
TWiN explains research showing that interaction between glioma cells and neurons in the brain shares mechanistic features with synaptic plasticity that contributes to memory and learning in the healthy brain.
TWiN 45: Acupuncture modulates the immune system
- December 13, 2023
- Tagged as: acupuncture, brain, dopamine, immune system, nervous system, neurobiology, neurology, neuron, neuroscience, sciatic nerve
TWiN discusses research showing that sciatic nerve activation with electroacupuncture at the sciatic nerve controls systemic inflammation and rescues mice from polymicrobial peritonitis, by inducing vagal activation of aromatic L-amino acid decarboxylase, leading to the production of dopamine in the adrenal medulla.
