Tim explains AI co-scientist, a tool released by Google, which it hopes to help scientists generate hypotheses and research proposals, and to accelerate the speed of scientific and biomedical discoveries. Hosts: Vincent Racaniello, Tim Cheung,
TWiN explains a study showing that when a mouse is confronted with an unconscious conspecific, it engages in behavior including tongue-dragging to resuscitate the animal via a tongue-brain connection. Hosts: Vincent Racaniello, Tim Cheung, and
TWiN discusses a study showing that repetitive injury reactivates HSV-1 in a human brain tissue model and induces phenotypes associated with Alzheimer’s disease. Hosts: Vincent Racaniello and Tim Cheung Subscribe (free): Apple Podcasts, Google
TWiN explains a study showing that while groups of neurons, form the basis for memory, astrocytes are key components of the adaptive reponse to learning experiences, and regulate the flow of information during circuit plasticity and memory reca
TWiN explains the identification of a brain circuit and periodic branch-specific neurotransmitter deployment that regulates organismal adaptation to photoperiod change. Hosts: Vincent Racaniello, Jason Shepherd, and Tim Cheung Subscribe (free):
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 Subscribe (free): Apple Podcasts, Google Podcasts, R
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, illumi
Mauro Costa-Mattioli returns to 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. Hosts: Jason Shepherd, Timothy Cheung,
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-a
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
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. Hosts: Vincent Racaniello, Timothy Cheung, and Vivianne Morrison Subsc
TWiN describes a study that reveals activation of endogenous retroviruses in oligodenroglia from patients with traumatic brain injury. Hosts: Vincent Racaniello, Jason Shepherd, and Timothy Cheung Subscribe (free): Apple Podcasts, Google Podc
TWiN explains 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. Hosts: Vincent Racaniello, Jason Shepherd, and Timothy Cheung Subscribe
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. Hosts: Vincent Racaniello, Jason S
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 dec
TWiN reviews a mouse model of ADHD to characterize hypersensitivity to pain, and that sensitization is further amplified in a pathological inflammatory state. Hosts: Vincent Racaniello, Jason Shepherd, and Timothy Cheung Subscribe (free): Appl
TWiN discusses a study of on the pathways that control opioid analgesic tolerance, a root cause of opioid overdose and misuse, which can develop through an associative learning. Hosts: Vincent Racaniello, Jason Shepherd, and Timothy Cheung Subs
TWiN explains how psychedelic drugs such as LSD, psilocybin, and MDMA, which are being explored for treating a wide range of neuropsychiatric diseases, reopen the social reward period for critical learning. Hosts: Vincent Racaniello, Jason Shep
Vivianne explains how early in Alzheimer’s disease, the brain attempts to counteract the increased excitatory drive caused by amyloid deposition, and that melanin-concentrating hormone, produced during sleep, is involved in this protective resp
Tim takes TWiN through two studies on the role of dopamine: that syllables are natural units of spontaneous behavior used by the brain to structure action, and that mesolimbic dopamine release conveys causal associations but not reward predicti
Junjie from Jason’s lab joins TWiN to discuss the observation that the cell gene PNMA2 encodes non-enveloped virus-like capsids that induce autoantibodies which underlie paraneoplastic syndrome. Hosts: Vincent Racaniello, Jason Shepherd, Timoth
TWiN explains the finding that immunity to commensal bacteria promotes sensory neuron regeneration via the cytokine interleukin-17A. Hosts: Vincent Racaniello, Ori Lieberman, Timothy Cheung, and Vivianne Morrison Subscribe (free): Apple Podcas
TWiN reviews the field of microgial research, which has advanced in recent decades but is constrained by nomenclature that is necessary but often implies specific functions. Hosts: Vincent Racaniello, Jason Shepherd, Timothy Cheung, and Viviann
TWiN answers listener questions about Alzheimer’s disease, glaucoma and the microbiota, Dravet’s Syndrome, schizophrenia, brain development, and chips implanted in the human brain. Hosts: Vincent Racaniello, Jason Shepherd, Timothy Cheung, and
Jason and Tim review the use of an implanted chronic deep brain sensing and stimulation device to carry out biomarker-driven closed-loop therapy that resulted in a rapid and sustained improvement in depression. Hosts: Jason Shepherd and Timoth
