Final answer:
The autopsy disclosed abnormalities in Mr. Blackwell's brain, including a cavity filled with serous fluid in the perisylvian region and loss of volume in the left cerebral hemisphere, leading to the brain weighing less than normal.
Step-by-step explanation:
The autopsy on Mr. Blackwell's body revealed several significant findings. Firstly, the brain weighed less than normal, which was attributed to a loss of volume in the left cerebral hemisphere. Upon closer examination, there was a softened area in the perisylvian region containing a cavity filled with serous fluid.
The autopsy noted volume loss in the gyri, subcortical perisylvian area, insula, and part of the striate nucleus, indicating that Mr. Blackwell suffered from substantial neurological deficits. These findings suggest that Mr. Blackwell may have experienced a cerebral injury or disease affecting his brain before death.
