== Notable experiments == Throughout the history of cognitive neuroscience, many notable experiments have been conducted. For example, the mental rotation experiment conducted by Kosslyn et al., 1993,<ref name=":1">{{Cite journal |last1=Kosslyn |first1=Stephen M. |last2=Digirolamo |first2=Gregory J. |last3=Thompson |first3=William L. |last4=Alpert |first4=Nathaniel M. |date=1998 |title=Mental rotation of objects versus hands: Neural mechanisms revealed by positron emission tomography |journal=Psychophysiology |language=en |volume=35 |issue=2 |pages=151β161 |doi=10.1111/1469-8986.3520151 |pmid=9529941 }}</ref> indicated that the time it takes to mentally rotate an object via imagination takes the same amount of time as actually rotating it; they found that mentally rotating an object activates parts of the brain involved in motor functioning, which may explain this similarity.<ref name=":1" /> Another experiment is describes the two mechanisms of processing visual attention: bottom-up attention, and top-down attention.<ref>{{Cite journal |last1=Itti |first1=L. |last2=Koch |first2=C. |date=March 2001 |title=Computational modelling of visual attention |journal=Nature Reviews. Neuroscience |volume=2 |issue=3 |pages=194β203 |doi=10.1038/35058500 |pmid=11256080 |url=https://resolver.caltech.edu/CaltechAUTHORS:20130816-103152921 }}</ref> They define bottom-up attention is the brain visually processing salient images first, and then the surrounding information, while top-down attention involves focusing on task-relevant objects first. The researchers found that the ventral stream focuses on visual recognition, the dorsal stream is involved in the spatial information concerning the object. As experiments in cognitive neuroscience, what these have in common is that the researchers are measuring activities or behaviors that we can see, and then determining the neural basis of the function and what part of the brain is involved.
