It’s another neuro news roundup! Zombie genes: fluff versus fact! Rub some trees with sloth bears! Avoid dying from COVID with Neanderthals! And is the Morris Water Maze traumatic? Also, castrated cats.
- Scent-marking behavior by female sloth bears during estrus (Khadpekar et al., 2021)
- Clarification: All mentions of “genital rubbing” in this segment refer to the act of rubbing genitals on a surface (e.g., a tree).
- A genomic region associated with protection against severe COVID-19 is inherited from Neandertals (Zeberg & Pääbo, 2021)
- Selective time-dependent changes in activity and cell-specific gene expression in human postmortem brain. Reported like a boss by Jacqueline Carey. (Dachet et al., 2021)’
- Recent study on how dissociation affects a cell’s transcriptional profile:
- Tissue damage induces a conserved stress response that initiates quiescent muscle stem cell activation. Cell Stem Cell. (Machado et al., 2021)
- For more on cell responses to isolation procedures, see:
- Transcriptional Profiling of Quiescent Muscle Stem Cells In Vivo. Cell Reports. (van Velthoven et al., 2017)
- Prolonged epigenetic and synaptic plasticity alterations following single exposure to a psychedelic in mice (De la Fuente Revenga et al., 2021)
- The differential calibration of the HPA axis as a function of trauma versus adversity: A systematic review and p-curve meta-analyses. Preprintlandia. (Hosseini-Kamkar, Lowe, Morton, 2021)
- Correction: the dark blue classic Tootsie Roll Pop flavor is either blue raspberry or grape; not blueberry.
- Lucky Millinder (1941) Big Fat Momma
- Note: The outro song is not the specific song Leah was thinking of. It is, however, as the kids say, a bop.
Note: The outro meowing is from a female cat in estrus. We are still working on obtaining audio from our new favorite male cat.
