The Mysterious Workings of the Brain
20:12 - 36:16 (16:03)
Despite knowing a lot about the details and top-level questions of the brain, there are still basic questions about general neuroscience that remain unanswered, such as why we sleep. The understanding of the algorithms and computations in the brain circuits is intertwined with each other unlike in hardware and software systems.

The brain is comprised of specialized modules that are responsible for different functions such as vision and language, as confirmed by studies on brain lesions and functional MRI scans.
20:12 - 26:28 (06:15)
Summary
The brain is comprised of specialized modules that are responsible for different functions such as vision and language, as confirmed by studies on brain lesions and functional MRI scans. While these modules are very specific, it is unknown whether they work independently or collectively to form intelligence.

The cortex is responsible for different regions such as vision, audition, motor control, and language.
26:28 - 28:53 (02:25)
Summary
The cortex is responsible for different regions such as vision, audition, motor control, and language. Research has shown that the hardware and type of neurons across these regions look similar but solving the puzzles of how the cortex processes information still remains a challenge.
