Absolutely fantastic unit. Great breadth of content and very interesting too. Ramesh is one of the best, if not the best, lecturer i've had at uni thus far. He's both entertaining and very knowledgeable. It makes all the difference for the unit. He provides a great amount of resources in comparison to other units which have next to nothing. Instead of a textbook, you can use the notes he wrote himself, which are excellent. He knows every single students name (i'm not exaggerating), i only went to lectures a handful of times in semester (3-6) and he still somehow knew my name, i almost fell on the floor. We're all amazed how he does it but no one knows. It's certainly a nice touch. I think he may have also won a few teaching awards.
There is a lot of neurobiology (receptors, neurons, neurotransmitters, etc) near the start which transitions into the senses (hearing, vision, smell, etc) and finally muscles/movement.
Great unit. If you're thinking of taking physiology, i highly recommend it.
