Spindle neurons, also called von Economo neurons (VENs), are a specific class of neurons that are characterized by a large
spindle-shaped soma (or body), gradually tapering into a single apical axon in one direction, with only a single dendrite facing opposite. Other neurons tend to have many dendrites, and the polar-shaped morphology of spindle neurons is unique. A neuron’s dendrites receive signals, and its axon sends them.
Spindle neurons are found in two very restricted regions in the brains of hominids—the family of species comprising humans and other great apes—the anterior cingulate cortex (ACC) and the fronto-insular cortex (FI). Recently they have been discovered in the dorsolateral prefrontal cortex of humans.[1] Spindle cells are also found in the brains of the humpback whales, fin whales, killer whales, sperm whales,[2][3] bottlenose dolphin, Risso’s dolphin, beluga whales,[4] African and Asian elephants,[5] and to a lesser extent in macaque monkeys[6] and raccoons.[7] The appearance of spindle neurons in distantly related clades suggests that they represent convergent evolution, specifically an adaptation to larger brains.

“In June, 2015, Thrun’s team began to test what the machine had learned from the master set of images by presenting it with a “validation set”: some fourteen thousand images that had been diagnosed by dermatologists (although not necessarily by biopsy). Could the system correctly classify the images into three diagnostic categories—benign lesions, malignant lesions, and non-cancerous growths? The system got the answer right seventy-two per cent of the time. …Two board-certified dermatologists who were tested alongside did worse: they got the answer correct sixty-six per cent of the time.
…
“There’s one rather profound thing about the network that wasn’t fully emphasized in the paper,” Thrun told me. In the first iteration of the study, he and the team had started with a totally naïve neural network. But they found that if they began with a neural network that had already been trained to recognize some unrelated feature (dogs versus cats, say) it learned faster and better. Perhaps our brains function similarly. Those mind-numbing exercises in high school—factoring polynomials, conjugating verbs, memorizing the periodic table—were possibly the opposite: mind-sensitizing.”
