  Everyone deserves an obituary, but this woman especially.

    No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition. Which just makes me want to share it again: www.nature.com/articles/d41...
    

    Gladys Mae West obituary: mathematician who pioneered GPS technology

    She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

  Why are we spending hundreds of millions of dollars on bringing in new people when we can't fund the ones we have?

    13% success rates at #CIHR, is a really 87% fail rate for>4000 scientists. At a time when 🇨🇦 is investing millions to recruit more scientist into a broken funding environment. 🇨🇦, U need a strong science foundation 2 attract success. #CIHR, fix your science foundation, it is eroding in real time

  While humans spontaneously dance to a beat, the evolutionary origins of this ability remain debated. Behavioral work has shown that primates can move to auditory rhythms after training. Our question was: How does this association emerge in the brain? www.biorxiv.org/content/10....
  

  Reward-driven emergence of auditory pattern encoding in the primate motor system

  The ability to anticipate rhythmic patterns is fundamental to human experience, enabling music appreciation, speech comprehension, and dancing in sync to music. How the brain learns to use acoustic information to guide motor behavior remains a key question whose neural underpinnings and evolutionary origins are debated, especially in non-human primates. To understand how brain areas involved in motor control naively respond to predictable tone patterns, we recorded large single neuron populations across primary somatosensory (S1), primary motor (M1), dorsal premotor (PMd), supplementary motor (SMA), pre-supplementary motor (preSMA) cortices, globus pallidus interna (GPi), and medial geniculate body (MGB) of a rhesus monkey. During passive listening (Experiment 1) with a reward only at the end of each trial, primarily the MGB, not motor areas, responded to the auditory tone patterns, ruling out the spontaneous entrainment of motor activity to auditory patterns. Almost all areas robustly

  Using high-density Neuropixels probes, we recorded from neural populations across the motor and auditory systems of a rhesus macaque – first during passive listening to see how these circuits respond to auditory patterns.

  We found that motor areas do not spontaneously respond to auditory patterns during passive listening, but care a lot about trial structure and reward.
