- LIP's counterpart in humans
- fMRI studies show that IPS activity increases when covert attention is directed toward a particular stimulus (Corbetta & Schulman, 1998)
- Transcranial magnetic stimulation studies show that "...interfering with the normal function of IPS through transcranial magnetic stimulation (see Chapter 2) makes it difficult for people to voluntarily shift their attention (Koch et al., 2005)" (Breedlove & Watson, 2017). 

Intraparietal Sulcus (IPS)

- Voluntary, top-down control of attention in monkeys 
- "...Activity of LIP neurons is correlated with the direction of attention to particular locations, and it is enhanced regardless of whether the attention is directed toward visual or auditory targets (Bisley and Goldberg, 2003; J. Gottlieb, 2007)" (Breedlove & Watson, 2017). 
- LIP encodes a salience map (Bisley & Goldberg, 2006; Ipata et al., 2006)
- Ventral LIP - direct attention; dorsal LIP- eye movement planning 

Washtenaw Community College

- Function: Controlling attention 
- According to Wurtz et al., 1982, more parietal cells fire when monkeys engage in covert attention.
