Forming memories | Neuro-patch
The contents of episodic memory (but not other types of memory) are formed in the medial temporal lobe (the hippocampus and neocortical areas adjacent to it, including the entrorhinal area). This part of the brain seems to pick out moments of our conscious experience and commit them to memory. A recent paper looks at individual neurons involved in this memory formation. (Matias J. Ison, Rodrigo Quian Quiroga, Itzhak Fried. Rapid Encoding of New Memories by Individual Neurons in the Human Brain. Neuron, 2015; 87 (1): 220 DOI: 10.1016/j.neuron.2015.06.016) The researchers used the method of asking cooperation from patients who are awaiting surgery for epilepsy and have been fitted with electrodes in a particular area of the brain to locate the exact focus of the epilepsy. This is probably the only ethical way in which studies can be done involving the recording from individual neurons in humans. It is thought that memories are established by associations. But it is a puzzle how
