Human Neurons Are Different From Animal Ones, Researchers Say

A Canadian research team got a rare chance to compare live brain tissue from donors undergoing surgery with that of rodents

Most neuroscience studies on live neurons depend on animal neurons. But a group of researchers in Canada got the opportunity to study live neurons from 66 human donors undergoing brain surgery for epilepsy and tumors. So they had a chance to compare human with rodent neurons: “The goal of this study was to understand what makes human brain cells ‘human,’ and how human neuron circuitry functions as it does,” says Dr. Taufik Valiante, neurosurgeon, scientist at the Krembil Brain Institute at UHN and co-senior author on the paper. University Health Network, “Researchers Identify Unique Characteristics of Human Neurons” at Neuroscience News (May 3, 2021) Looking specifically at live human cortical pyramidal cells, they found “notable and unexpected differences between their Read More ›
