It's known that neural tissue can routinely re-generate in several species. The subject is intensely researched because of its potential to re-grow neural tissue which has been damaged, either due to disease (e.g., , etc), or by physical injuries.
There is currently no agreement as to whether new neural cells are (or could be) generated in adult humans :
The numbers of neurons born in the human hippocampus remains controversial; some studies have reported that in adult humans about 700 new neurons are added in the hippocampus every day, while other studies show that adult hippocampal neurogenesis does not exist in humans, or, if it does, it is at undetectable levels.

It's not presently known if humans can regrow brain cells : See :
“Our brains may be able to make new neurons throughout adulthood” New Scientist 25 March 2019
“We may be unable to grow new brain cells after we enter adulthood” New Scientist 16 Feb 2022.
Note: There is also a debate about whether adult learning induces the growth of new brain cells. The idea has not as yet been proven or disproven.
