The "bottom-up" process by which our sense receptors receive stimulus energy from the environment, transduce them into a neural signal, and send them to higher brain areas is known as

Sensation.

Explanation:

The sensory receptors are responsible for the detection of stimuli. The bottom up and top down control are the two important processing that helps in the introductions of sensory information in the body.

Sensation is the process by which the organisms detect the internal as well as external stimuli. The three main process that are involved in sensation are detection of stimuli from the environment, the change of stimuli in electrical signal and then received by the brain for further processing.

Thus, the correct answer is sensation.
