See The Human Brain Like Never Before<\/span><\/p>\n

A decade ago, a small and unassuming brain sample arrived at Dr. Jeff Lichtman\u2019s lab at Harvard University. Measuring less than a grain of rice, the 1 cubic millimeter of tissue contained 57,000 cells and 150 million synapses, each one a vital part of the brain\u2019s intricate communication network.<\/p>\n

Neurons from the anterior temporal lobe, color-coded by size and type, reveal the six distinct layers of the cortex.<\/em><\/a><\/p>\n

Now, after a decade of collaboration with Google scientists, a monumental dataset\u2014with 1,400 terabytes\u2014has turned into the most detailed map of the human brain ever created.<\/p>\n

\u201cA terabyte is, for most people, gigantic, yet a fragment of a human brain\u2014just a minscule, teeny-weeny little bit of human brain\u2014is still thousands of terabytes,\u201d Lichtman said in a National Institutes of Health report<\/a>.<\/p>\n

The detailed 3-D reconstruction reveals beautiful structures in the brain. Neurons forming dozens of connections, mirror-image neural pairs, and networks far more complex than expected, are just some of the groundbreaking discoveries.<\/p>\n

\u201cI remember this moment, going into the map and looking at one individual synapse from this woman\u2019s brain, and then zooming out into these other millions of pixels,\u201d said Viren Jain, a senior scientist at Google in Nature Magazine<\/a>. \u201cIt felt sort of spiritual.\u201d<\/p>\n

The map, now part of an open-access dataset online, opens the door to new understandings of human cognition, psychiatric disorders, and the architecture of our minds.<\/p>\n

\u201cThere is the saying that \u2018A map of synaptic connections is necessary but insufficient to understand the brain.\u2019 In its current form it is still missing a lot of important information, but it is a step in the right direction,\u201d Daniel Berger, a scientist in the Lichtman lab, told The Epoch Times.<\/p>\n

Excitatory neurons, color-coded by size, with red being the largest and blue the smallest. Cell cores range from 15 to 30 micrometers.<\/p>\n

<\/a><\/p>\n

A single white neuron receives signals from more than 5,000 blue axons, with green synapses marking the points where the signals transfer.<\/p>\n

<\/a><\/p>\n

Neurons with long dendrites and dendrite spine. In very rare cases, a single axon (blue) made repeated synaptic connections (yellow) with a target neuron (green).<\/p>\n

<\/a><\/p>\n

One unexpected discovery in the study was the presence of \u201caxon whorls\u201d\u2014tangled loops of blue axons\u2014which typically transmit signals away from nerve cells. These structures were rare in the sample and sometimes appeared to be resting on yellow cells. Their purpose remains unclear.<\/p>\n
