Thalamus is a group of nuclei located deep inside the brain, well known for its sensory and cognitive functions. However, its role in the reward and behavior regulation is less explored. In this case series, we have presented four cases with inappropriate sexual behaviors (ISB) that are temporally related to thalamic infarction. We have discussed about the limbic part of thalamus and its extensive connections with other regions in regulating sexual behaviors. Although in all the four cases described there was underlying cognitive impairment that can itself increase the risk of ISB, there was potential contributing role of thalamic lesions.
