The field of language research has seen tremendous progress in the last two decades. Advances in neuro-imaging and stimulation mapping have changed the way we conceive the neural basis of speech and language processing. In the past, the Wernicke-Lichtheim model was the most influential model explaining the neuro-anatomical basis of language. More recently, the concept of dual stream language processing has emerged, wherein separate dorsal and ventral networks are synergistically involved in phonological (sound to articulation) and semantic (sound to meaning) processing respectively. In this review article, we highlight new insights and approaches to the neurobiology of language, across different aspects of language processing like perception, comprehension, production, hemisphere lateralization, role of subcortical structures and effect of damage to language networks.
