IB Psychology: Neurotransmission

Nerve cells, called neurons, are one of the building blocks of behaviour. It is estimated that there are between 10 and 100 billion neurons in the nervous system and that neurons make 13 trillion connections with each other. The neurons send electrochemical messages to the brain so that people can respond to stimuli—either from the environment or from internal changes in the body.The following video explains how the...

Antonova et al is a great study. Will you be posting more information or adding it to your list of key studies? (See my comment in Facebook group.) Thanks.

Ian, I can add it to "key studies."

Hi John, I'm curious about one comment regarding Antonova... in the original, it states that there was "no significant difference in performance accuracy, as measured using the mean displacement error", but you mention that the task took more time. This time concept would make sense, but I can't seem to figure out where the original study mentions it, as it was a discussion point with students recently. Can you point me to it?

Dear Trevor,

Good question. I am just rereading the text and agree that this is not the case. I will fix the text, but I will seek out my other sources with Antonova cited which made reference to this. Thanks for catching this.

Thanks, John. I'd been thinking that I must've missed something, as it seemed to make sense and would be consistent with Rogers and Kesner and other similar studies regarding differences in speed/error rates for different conditions. Am I reading correctly in believing that the lack of time difference/levels of error between the conditions has to do with the fact that the participants in Antonova et al extensively practiced with the VR maze prior to scanning? It seems like a plausible explanation at least.
