Researchers map brain networks involved in word retrieval

How are we able to recall a word we want to say? This basic ability, called word retrieval, is often compromised in patients with brain damage. Interestingly, many patients who can name words they see, like identifying a pet in the room as a "cat", struggle with retrieving words in everyday discourse.
