The physical basis of memory is a pathway through the brain called a memory trace, in which new synapses have formed or existing synapses have been modified to make transmission easier. true or false

True

Explanation:

Memory is formed by creating new neural pathways from stimuli we receive (smell, vision, auditory etc) to the brain where the pereception of  it occurs.

Memory is defined as ability of the brain to encode, store, and retrieve information when needed. Memory forming is actually information processing that includes:

•  sensory processor -  sensing the information from the outside world ( chemical and physical stimuli)

•Working memory (short-term memory) -  encoding (stimuli information) and retrieval processor (from previously stored material)  

•Long-term memory - to store data through systems.
