Whence did SWEDENBORG get all this? Whence the whole of this doctrine
of localizations? In his first great anatomical work, ›Œconomia Regni
Animalis›, nothing is said about it; first in his last anatomical work,
›De Cerebro›, is it advanced, and then — — — quite finished! One is at
first glance tempted to think that he had succeeded in finding some new
clinical experiences, upon which he could found this doctrine. For he had
not even finished the account of the function of the brain’s anterior
region, before interjecting: ›Therefore, if this portion (the anterior
region) of the cerebrum is wounded, then the internal senses—imagination,
memory, thought—suffer; the very will is weakened, and the power of its
determination blunted. This is not the case if the injury is in the back
part of the cerebrum› (›The Brain›, No. 88). But afterwards he does not
bring forward (in ›De Cerebro›) any observations which could serve as
proof with regard to this. And if one examines the cases he has referred
to in his preceding works, one cannot possibly arrive at the localization
of the psychic functions which he has here (in ›De Cerebro›) sketched;
for the evidence concerning the _position_ of the injuries in the cortex
are entirely too scanty and incomplete. But if we consult the _original
descriptions_, we find there many other and more particular data than
those quoted by SWEDENBORG when he was only concerned in explaining the
function of the cortex as a whole. WEPFER, for instance, reports in his
›Historiæ apoplecticorum› concerning the woman seventy years of age, who
suddenly _lost the power of speech_, that the cavity, filled with blood,
which was found in the cortex at the autopsy, was located in the right
hemisphere, _just behind the forehead_ (›ad frontem fere antrorsum›), and
that it extended rather far both backwards and upwards; even measurements
were given (length 8, breadth 4, depth about 2 uncias). It was also
stated that the blood-vessels whose bursting caused bleeding belonged
to the antero-lateral branches of the carotid artery in the brain. It
is also mentioned that no changes were found in the left hemisphere of
the brain; and from the clinical account it appears that even after the
stroke the woman was able to move the extremities of the right side.[74]
— — — All this indicates quite evidently that the lesion of the cortex
was situated in the anterior region of the brain!
And PACCHIONI reports concerning the youth, who was afflicted with the
right-sided _facial paralysis_, that even the extremities of the right
side were somewhat paralysed, and that the cyst, which at the post
mortem examination was found on the left hemisphere, extended _from the
crown to the region of the temple_ (›a capitis vertice in temporalem
regionem›).[75] Thus this case also furnishes an unmistakable indication
that the cortical lesion was situated in the anterior region of the brain.
