Investigation of the Uncanny Valley Hypothesis and affective experience requires an understanding of the hypothesis' dimension of human likeness (DHL). This protocol allows representation of the DHL and examination of categorical perception. Use of the same stimuli and fMRI to distinguish brain regions responsive to physical and category change is illustrated.

Here, we present a systematic approach for developing physiologically relevant, sensitive and specific in vivo assays for interpreting variation in human pathology. Transient genetic manipulation via microinjection of WT and mutant human mRNA and morpholino (MO) antisense oligonucleotides harness the tractability of the developing zebrafish embryo to rapidly assay pathogenic mutations, especially, but not exclusively, in the context of human developmental disorders.

Protocol for propagation of dissociated high grade glioma surgical specimens in serum-free neurosphere medium to select for cells with cancer stem cell phenotype. For specimens that fail to grow as neurospheres, an alternative protocol is suggested. A paraffin embedding technique for maintaining the 3D neurosphere architecture for immunocytochemistry is described.

From the derivation of murine fallopian tube organoids, their genetic modification to recapitulate human HGSOC genetics, and their introduction in the ovarian bursa of syngeneic mice for in vivo development of tumors.
FAQs
A Model Human-likeness Grade can be examined by comparing several forms of model output with corresponding human measurements from the same task. Behavioral evidence may include choices and response patterns, whereas neural evidence concerns similarities in brain activity. Considering these dimensions separately helps show whether a model resembles human performance broadly or only matches one observable aspect.
Similarity in outputs does not establish identical internal processing. A model may reproduce human choices, response patterns, or brain activity while reaching those outcomes through different computational operations. Therefore, a high grade supports a model's biological plausibility and can strengthen hypotheses about neural mechanisms, but researchers must avoid treating behavioral or neural resemblance as proof of shared implementation.
The evaluation can focus on human choices, response patterns, or brain activity, depending on the matched task and the scientific question. Choices reveal similarities in decisions, response patterns capture how performance unfolds, and neural measurements provide evidence about correspondence with brain responses. Comparing these distinct outputs can clarify which features of human information processing the model reproduces.
Matched tasks provide the basis for a meaningful comparison because the model and human participant must produce outputs in comparable circumstances. Researchers can then examine whether their choices, response patterns, or brain activity align during the same task. If the task or measured output differs, the resulting comparison gives less direct information about how closely the model captures human processing.
A basic workflow begins with collecting human data during a specified task, generating model outputs for that same task, and comparing corresponding results. The analysis may examine behavioral choices, response patterns, or brain activity. Researchers then use the observed similarities and differences to assess biological plausibility and identify aspects of information processing that the model does or does not capture.
It is useful when researchers want to determine whether a model captures human patterns in a particular cognitive domain. For perception, learning, memory, or decision-making, comparisons with human task data can reveal where artificial processing resembles or departs from human behavior or neural responses. These findings help evaluate competing models and guide hypotheses about the mechanisms underlying cognition.
Differences can identify specific aspects of human information processing that the model fails to reproduce. A model may match behavioral choices while departing from human response patterns or brain activity, indicating that its agreement is limited to certain observations. Such discrepancies help researchers refine models and distinguish broad performance similarity from a more informative account of biological plausibility.
