1Department of Neurology, Indiana University, Indianapolis, IN, United States.
Abstract:
There are few reports of patients with parietal lobe epilepsy. One of the largest series, from the Montreal Neurological Institute (MNI), reported that patients with epileptogenic areas in the parietal cortex behind the postcentral gyrus comprised 6% of patients with refractory focal epilepsy treated surgically at the MNI between 1929 and 1988. Since then several other institutions have reported their experience with the evaluation and treatment of patients with parietal lobe epilepsy. This chapter reviews the functional anatomy of the parietal lobe, electroclinical manifestations and surgical outcome of parietal lobe epilepsy, and recent advances in the evaluation of patients with refractory focal epilepsy.
Insights
Parietal lobe epilepsy is rare, accounting for 6% of surgically treated refractory focal epilepsy cases at the Montreal Neurological Institute. This review covers its anatomy, symptoms, and treatment outcomes.
Area of Science:
- Neurology
- Neurosurgery
Background:
- Parietal lobe epilepsy is infrequently reported, representing a small percentage of refractory focal epilepsy cases.
- The Montreal Neurological Institute reported 6% of surgically treated refractory focal epilepsy patients had epileptogenic zones in the parietal cortex.
Purpose of the Study:
- To review the functional anatomy of the parietal lobe.
- To discuss electroclinical manifestations and surgical outcomes for parietal lobe epilepsy.
- To highlight recent advances in evaluating refractory focal epilepsy.
Main Methods:
- Literature review of parietal lobe epilepsy cases.
- Analysis of functional anatomy relevant to epilepsy.
- Synthesis of electroclinical features and surgical outcomes.
Main Results:
- Parietal lobe epilepsy constitutes a specific subset of refractory focal epilepsy.
- Surgical treatment outcomes for parietal lobe epilepsy vary.
- Advances in diagnostic techniques are improving patient evaluation.
Conclusions:
- Parietal lobe epilepsy requires specialized understanding due to its unique characteristics.
- Comprehensive evaluation integrating anatomical, electrophysiological, and clinical data is crucial.
- Continued research into surgical and diagnostic advancements is essential for improving patient care.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
