The only biologist to propose a radically novel approach to these questions is Dr Rupert Sheldrake. In his book A New Science of Life Sheldrake rejected the idea that the brain is a warehouse for memories and suggested it is more like a radio receiver for tuning into the past. Memory is not a recording process in which a medium is altered to store records, but a journey that the mind makes into the past via the process of morphic resonance.
I like this, the brain as a radio receiver instead of a big warehouse, interesting?
Sanskrit 'citta', 'consciousness', is also translated as 'heart' or 'mind', not as 'brain'. Brain is just an interface. Memories are stored in the subtle body and accessed under the supervision of Paramatma. Look at the model described here: http://www.veda.harekrsna.cz/encyclopedia/tattvas-1.htm#2
Yes, brain is the hardware, but what kind of hardware is it? It is common to think that our memories are stored there. After all, we don't have memories of anything before this brain! But using the brain as the radio receiver is very interesting, how this brain, gross physical thing can access the subtle physical elements of memory.
Yes. Legs, etc. are all interfaces for jiva to operate in the material world. Matter itself is jada, inert.
