Brain and quality of experience are important; for example, there is substantial evidence that animals raised in enriched environments have thicker cerebral cortices, indicating a higher density of synaptic connections, than animals whose levels of stimulation are restricted. The functions of the brain depend on the ability of neurons to transmit electrochemical signals to other cells, and their ability to respond appropriately to electrochemical signals received from other cells. The electrical properties of neurons are controlled by a wide variety of biochemical and metabolic processes, most notably the interactions between neurotransmitters and receptors that take place at synapses. Neurotransmitters are chemicals
Pinky and the Brain mice are foiled by trying to speak "New York cabbie" and end up going in circles, the gag credit word was "anophelosis" defined as "morbid state due to extreme frustration". Another common element in nearly each episode is the following exchange (often referred to by the acronym "AYPWIP"): Brain: Pinky, are you pondering what I'm pondering?Pinky: I think so, Brain, but... Pinky's response ends with a non-sequitur such as, "we're already naked", "isn't a cucumber that small called a gherkin?" or "if they called them sad meals, kids wouldn't buy them." Brain would then become furious, often bashing Pinky over
