Vanessa The most interesting point for me is that brain computer interface (BCI) makes it possible for tetraplegic patients to use their thoughts to control artificial limbs. Specifically, a tetraplegic woman Cathy Hutchinson was able to drink a cinnamon latte by using her thoughts to control a robotic arm in 2012. This works by implanting a tiny sensor (the size of a baby aspirin) on the surface of the brain. This tiny sensory then picks up electrical impulses from nearby neurons, which can be translated by BCI into algorithms and command robotic/articial limb movements. This is a really fascinating and exciting development as it can definitely be used to help people suffering from paralysis to be able to do things on their own in the future.

Sarah From going through the lecture and textbook chapters for this week I would have to say the most interesting point that was made from this week would be the connections to the prefrontal cortex (PFC). I found it very interesting learning about the direct input of the PFC; which explains how the thalamus is the largest input of the PFC (primarily from mediodorsal nucleus) and the Limbic regions of the PFC are the amygdala, hippocampus and ventral tegmental area (VTA). Another interesting point to add is the PFC sends projections back (direct outputs) to many of the same regions from which it receives inputs and it sends direct outputs to the basal ganglia. These are some of the interesting points of the PFC that I found intriguing in this week’s lecture. I look forward to learning more about the PFC and how much it has an effect on us.
