There appear to be very few standards that have been published either by the State of Connecticut's department of education or by the city of New Haven. In my own teaching I try to cover the major body systems found in the human body. The closest published standards that I have found which cover the brain and nervous system are for biology and are as follows:
Connecticut State Science Core Framework, page 34
"The nervous system mediates communication between different parts of the body and the body's interactions with the environment."
"The neurons transmit electrochemical impulses."
"Sensory neurons, interneurons and motor neurons all have a role in sensation, thought and response."
