Activating memory cells at the top of the hippocampus appears to function like exposure therapy, a psychological treatment in which a person is exposed in a safe and controlled environment to something that triggers a bad memory, fear, or other unpleasant response.
Measles may throw the body into a much longer-term state of 'immune amnesia,' where essential memory cells that protect the body against infectious diseases are partially wiped out, said the study appeared in the journal Science.
The associated memory cells that fired at the time - in three different parts of the brain, the hippocampus, the prefrontal cortex and the basolateral amygdala, which stores emotional associations of memories - were labeled.
The weight matrix dimension input by the input gate, the output gate, and the cell state at this time is ni * nc, and the weight matrix dimension at the last time is nc * nc, and the output matrix dimension connected to the output of the neural network is no*nc, where ni and no are the dimensions of the input and the output, respectively, and nc is the number of memory cells. We can easily get the following formula:
