What are alternatives to the theory of excitatory-inhibitory balance for brain disorders?
5 answers
Alternative theories to the excitatory-inhibitory (E/I) balance model for brain disorders include the consideration of multidimensional neural circuit alterations. These alterations may involve changes in neural firing rates, correlations, and the sensitivity of different cellular components within the circuit. Additionally, the concept of a transient E/I shift during early development leading to neurological disorders suggests that the communication impairment between neurons, rather than a simple E/I imbalance, could be a key factor in symptom manifestation. Furthermore, the idea of individualized neurostimulation interventions based on the E/I balance hypothesis for post-stroke rehabilitation highlights the importance of targeting specific brain regions to restore functional balance and facilitate recovery. These alternative perspectives emphasize the need for higher-dimensional models that can capture the complex computational functions of neural circuits in various brain disorders.

What were the main findings of Rayner and Frazier's (1987) study on parsing temporarily ambiguous complements?
4 answers
Rayner and Frazier's (1987) study focused on parsing temporarily ambiguous complements. The study highlighted that the comprehension system initially uses limited information, such as major syntactic categories and phrase-structure rules, to form an initial interpretation. This interpretation is later revised based on additional sources of knowledge, including lexically-specific information and discourse context. Additionally, the study contrasted the garden-path model, which suggests a two-stage process with initial constraints and delayed revision, with the constraint-based approach that emphasizes continuous evaluation of multiple syntactic alternatives in parallel, with competition among these alternatives during processing. The findings underscored the importance of integrating various constraints, including event plausibility, in resolving direct object/sentence complement ambiguities during sentence processing.
