Meet the Rosehip Neuron: A Newly Discovered Cell in the Human Brain | Smart News | Smithsonian

So what, exactly does the rosehip neuron do? That’s not quite clear. The cells make up about 10 percent of the neocortex, the last part of our brain to evolve which is associated with sight and hearing. Rosehip appears to be an inhibitory neuron, which regulates the flow of information to certain parts of the brain. Saplakoglu reports the rosehips seem to connect to pyramidal neurons, an “excitatory” neuron that makes up about two-thirds of the neuron cells in the neocortex.

“It has these really discrete connections with [pyramidal] neurons,” says Bakken. “It has the potential to sort of manipulate the circuit in a really targeted way, but how that influences behavior will have to come in later work,” Bakken tells Andrea Morris at Forbes.
