First use of fluorescein sodium guided resection

Fluorescein sodium guided resection

The first use of fluorescence for brain tumour surgery was in 1948 by G.E. Moore 1) using fluorescein sodium, a strongly fluorescing and non-toxic agent.

First description of Parsonage-Turner Syndrome

The Parsonage Turner syndrome is named after Maurice Parsonage and John Turner and published in the Lancet by Parsonage and Turner .

The condition, subsequently coined Parsonage-Turner Syndrome, had been previously described in the literature as far back as 1897 with many similar clinical presentations of the syndrome reported prior to the extensive study of the syndrome by Parsonage and Turner.

Parsonage Turner syndrome is also known as acute brachial neuropathy and acute brachial radiculitis.

Other names used are Parsonage–Aldren–Turner syndrome, neuralgic amyotrophy, brachial neuritis, brachial plexus neuropathy, or brachial plexitis.

Update: Primary motor cortex

www.utdallas.edu_tres_integ_mot2_2_08.jpgThe primary motor cortex in the posterior frontal lobe (Brodmann area 4) was first described by David Ferrier in 1874, who used electrical stimulation to map the cortical areas responsible for movement in monkeys 1).

Since these initial findings, the description of this area has evolved to include the concept of a somatotopic map, wherein different parts of the body are represented individually on the primary motor cortex, as observed by Penfield and Boldrey 2)

David Ferrier has died

Sir David Ferrier FRS (13 January 1843 – 19 March 1928) was a pioneering Scottish neurologist and psychologist.

The primary motor cortex in the posterior frontal lobe (Brodmann area 4) was first described by David Ferrier in 1874, who used electrical stimulation to map the cortical areas responsible for movement in monkeys 1).

Taylor Haughton line

In 1900 Taylor and Haughton described a technique to define a line on the scalp directly above the central fissure 1)

1. Draw a Nasion-Inion line ( Nasion – Just below Glabella and Inion -External Occipital protruberance)

2. Divide the Nasion-Inion line in to 25%, 50% and 75%

3. Bregma is the point between the 25% and 50% points and Lambda is at 75% point

4. Sylvian fissure is drawn from the orbitotemporal angle (A point of depressin where eyebrow ends) to the 75% point on naso-inion line.

5. Draw a line perpendicular to the root of the zygoma starting at preauricular point

6. Central sulcus is drawn from 54% point on naso-inion line to the point where the sylvian line cuts the perpendicular line
