Which colours can we see best?
A normal human colour vision has three types of cones: Red, green and blue.
These types of cone are mostly sensitive to a specific wavelength of visible light. However, the sensitivity of the cones overlaps, so a particular wavelength of light may stimulate two types of cone.
What do you think guys?

Memory
Explain the role of Long Term Memory LTM.
Long-term memory is intended for storage of information over a long time. Information from the working memory is transferred to it after a few seconds.
There are two types of LTM :
Episodic memory represents our memory of events and experiences in a serial form. It is from this memory that we can reconstruct the actual events that took place at a given point in our lives.
Semantic memory, on the other end, is a structured record of facts, concepts and skills that we have acquired.
