Henry John Markram (xxxxxxx, 28 de marzo de 1962) es un neurocientífico israelí, catedrático del Instituto de xxxxx de la École Polytechnique Fédérale de Lausanne (EPFL) de Suiza. Markram es director del proyecto Blue Brain y fundador del proyecto cerebro humano.

Markram se graduó en Historia y Filosofía de la Ciencia por la Universidad de Ciudad del Cabo, Sudáfrica, y se doctoró en Neurobiología del Instituto Weizmann, en Israel. En el marco de su tesis doctoral descubrió el vínculo entre la acetilcolina y los mecanismos de memoria, demostrando que la acetilcolina modula al receptor primario vinculado con la plasticidad sináptica.

Henry Markram obtained his Bachelor of Science degree in Physiology and the History and Philosophy of Science from the University of Cape Town, South Africa and his PhD in Neurobiology from the Weizmann Institute of Science, Israel in 1991, under the supervision of Menahem Segal. During his PhD work, he discovered a link between acetylcholine and memory mechanisms by showing that acetylcholine modulates the primary receptor linked to synaptic plasticity.Henry Markram obtained his

Personal life[edit]Henry Markram obtained his

Born in South Africa, Markram is now an Israeli citizen. Markram met his current wife, fellow neuroscientist Kamila Markram (b. 1975), at the Max Planck Institute for Brain Research in Frankfurt. They moved to the École polytechnique fédérale de Lausanne together and, in 2007, founded Frontiers Media. Markram has been married twice and has a total of five children, one of whom, Kai, has autism.Henry Markram obtained his

Following his PhD, Markram went to the United States as a Fulbright Scholar at the National Institutes of Health (NIH), where he studied ion channels on synaptic terminals with Elise F. Stanley. As a Minerva Fellow he then went to the Laboratory of Bert Sakmann at the Max Planck Institute, Heidelberg, Germany, where he discovered calcium transients in dendrites evoked by sub-threshold activity, and by single action potentials propagating back into dendrites. He also began studying the connectivity between neurons, describing in great detail how layer 5 pyramidal neurons are interconnected.

Some of his work altered the relative timing of single pre- and post-synaptic action potentials to reveal a learning mechanism operating between neurons where the relative timing in the millisecond range affects the coupling strength between neurons. The importance of such timing has been reproduced in many brain regions and is known as spike timing-dependent synaptic plasticity (STDP).Henry Markram obtained his

Markram was appointed assistant professor at the Weizmann Institute of Science, where he started systematically dissecting out the neocortical column. He discovered that synaptic learning can also involve a change in synaptic dynamics (called redistribution of synaptic efficacy) rather than merely changing the strengths of connections. He also studied principles governing neocortical microcircuit structure, function, and emergent dynamics. Together with Wolfgang Maass he developed the so-called theory of liquid state machine, or high entropy computing.

In 2002, he moved to EPFL as full professor and founder/director of the Brain Mind Institute and Director of the Center for Neuroscience and Technology. At the BMI, in the Laboratory for Neural Microcircuitry, Markram continues to study the organisation of the neocortical column, develops tools to carry out multi-neuron patch clamp recordings combined with laser and electrical stimulation as well as multi-site electrical recording, chemical imaging and gene expression.Henry Markram obtained his

In 2013, the European Union funded the Human Brain Project, led by Markram, to the tune of $1.3 billion. Markram claimed that the project would create a simulation of the entire human brain on a supercomputer within a decade, revolutionising the treatment of Alzheimer's disease and other brain disorders. Less than two years into it, the project was recognised to be mismanaged and its claims overblown, and Markram was asked to step d
